Small Block & Big Block Chevy Specific - Junkyard heads

What is the best options for junkyards heads for a 94 TBI 350 truck?
I think I read somewhere TPI corvette heads where 1st then Camaro TPI. Anyone know for sure and what years? Thanks.

well 87-93 camaros/firebirds with 350's would work. i think vettes got the tpi in 86 and got the LT1 in 93 just like the f-bods. you might also consider some vortec trucks heads. if you do, grab the intake too. vortec heads would make alot more hp, but the torque wouldnt suffer like it might with those other 2.

vortecs, are great heads all around they make good torque and hp, but are limited to lift without modifications i think about .480, the tpi's started in the vets in 85, and in the f-bodies in 86, and the lt1 in vetts in 92 and fbodies 93, and the ls1 97 in vetts and 98 in fbodies the vets have always been one year ahead, none of the tpi heads are ganna be much of an upgrade all of them pretty much suck they are alittle better due to the non divider in the intake port like on the tbi heads also known as swirl port heads they really suck, your best bet would be to pick a set of vortecs up with a vortec intake so you can still use your tbi, there are abunch of guys on here that have vortecs for sale for a good price,

Is vortec heads and intakes a bolt on swap? What year trucks do I need to look for? Thanks.

I would go with a set of vortecs over those. Check out ebay, there's always several sets on there for lots less money. For cost comparison, I just picked up a set of 906 casting vortecs for $355 off ebay. They are fresh from the machine shop with new stainless valves/valve job and look brand new. After machining costs to cut the valve guides down & tap for screw in studs, I'll have ready to bolt on vortecs with comp beehive springs good to .600" lift for a total investment of ~$550. Now that's bang-for-the-buck, vortecs are hard to beat. :judge:

The vortec heads are close to 40 hp bolt on over the TBI heads. They are hard to beat for the $, if you are wanting brand new heads, www.SDPC2000.com has better pricing than Summit.

plus sdpc kicks ass. :judge:

What sort of casting numbers would someone look for? Any vortec heads particuarly better than others?

I'm looking on ebay and see quite a few 906, 12558062 and, 12558059.

But that aftermarket intake is what I need to put my factory TBI stuff on?

:) Yep! :)

062's the ones with the saw tooth pattern on the front. The 906's with the single hump have the restrictive hardened exhaust seat (more $$ to fix).

Stay away from the 059 castings, those are 305 vortecs. The 906 and 062 is what you're after, for all intensive purposes they will perform equally.

You can get a great set of vortecs for
12558060 Cast Iron L31 Vortec SB Chevrolet Cylinder Heads Assembled $269.75
At
http://www.sdpc2000.com/catalog/3129/GM-Performance-Parts-Cylinder-Heads.htm
They also offer a set that have the guides cut ans Z28 springs installed to increase lift
SD8060A2 Vortec SB Chevrolet Cylinder Head w/ Valve Spring Upgrade $339.95
Stock vortecs only allow a lift of 0.45 this upgrade will allow a lift of 0.525 for much less than having it done at a local shop. The base vortec head they sell is a new head cheaper than having old ones refinished at any local shop.
This is something to think about.
:drive:

This may be the best way to go,

This could be a way to go since it leaves nothing to chance. You do not have shipping costs to a dozen places, and you will not come up against something you need you didn't know about.

i was given 11 sets of 062 and 906 of vortec heads, but they seem to look identical everywhere, supposed to be the same, i believe.

Personally can't care less what the magazines say. Every set of 906's I have got had the hardened seat which hangs over into the exhaust flow exiting. Anyone that has truly worked with both castings can easily distinguish the stock seat difference. 062's are the standard production set to be looking for.

Intake flow between the 2 should (will IMO) be identicle. Exhaust flow can be equaled though $$'s spent.

"there are only two Vortec castings, 062 and 906. They both flow identical intake and exhaust. There is however, one variation on the 906 casting which has a single-angle Inconel exhaust seat for HD use on 3/4 and 1 ton trucks. This head flows only slightly less than the other two on the exhaust (the intake is the same for all Vortec heads) up to .100" lift, however the difference is so slight it doesn't appear to matter any. These are the heads I used."



****So basically IF you happen across a set of 906's or 062's that DO NOT have the pressed in hardened seat on the exhaust side you will be bucks ahead.*****

Feel like donating to the needy? Want to give me a set?

while were on the subject of vortecs, whats the deal with all of them cracking? Seems like Ive heard they all crack in the same spot sooner or later? :( :lurk:

The early ones had that problem. The new ones not so much. Like everything engine, Keep it cool, and do not run compression over 9.5-1 with cast iron. The weekness in these heasd comes between the valves from what I have seen. As cheap as they are, you are better off to buy new ones. they are cheap as dirt as far as heads go. Great performers though.

Sallee Chevrolet is a dealership! I gave you a link to their tech forum. I work with the vortec heads ALL of the time. One of my biggest customers runs the vortec 350's & the Mark VI BBC's on their compressor motors. These motors run 24 hrs per day and are going on 4 yrs of service without a rebuild. The motors only turn 2200-2400 rpms but to get the life out of them you HAVE TO KNOW how to build the heads properly. The 062 is the replacement part number for the 906 induction hardened valve seat cylinder heads. I work with the hardend press fit valve seat heads all of the time and there are not that many sets that have any sort of lip under the valve seats. :)

Are you retarded? 906's are the only casting with the hardened seat. So if you are in a wrecking yard and you run across a set of 906's and 062's get the 062's would be a good rule of thumb. The pressed in hardened seat is the lip retard. :) duh!. The 906's I have came across have HAD the hardened seat. I have got some of the worse misinformation from Stealerships. BTW 906's and 062's have BOTH been produced since 1996 with the 906's being the ONLY casting with the hardened seat. :judge:

WTF cares?

Man go recommend some more really funky erson grinds somewhere and stfu. :)

For the record, and you surely already know this since you work at a dealership...062 and 906 are part of a casting number, not a part number...

AND, at Scoggin Dickey we now have a more affordable heavy duty casting of the Vortec heads available! They have more meat around the areas that have been known to crack as well as a thicker deck. Stock sized valves with chromoly retainers and springs and machining good to .475" max lift are $569.00 per pair!!!

Similar good to .525" max lift are $623.90 per pair!
Finally, good to .600" max lift and setup for hydraulic roller are $709.90 for the pair!!

We've got them all in stock ready to ship! Give me a call, I have everything you need for your SBC's!

Stunningman do you know what the words "induction hardened" means? The 906 casting is a generalized partial casting number. They made bolth the hardened valve seat versions that have the pressed in valve seats and the induction hardened valve seats. Try a search so that you have a clue next time you ramble on about rumors of the "bad vs the good" set of heads. For me I think I would listen to SDPC's performance center, who actually sells a ton of these heads every day!

I think its pretty clear I know this except to you for obvious reasons.

LMAO at you telling me to search. As usual you skate the issue which is 906's were the only head produced with the hardened seats. So given a choice of casting numbers I would buy the 062's. Of course you also skate the issue of the seat hanging into the port as usual. Which I will post pics of later today to prove your a total tard. because you state it doesn't.

SDPC said nothing to me he is selling heads he corrected someone else on the part number versus the casting number, I can care less. As far as they sell a lot of these heads thats great. Its not unheard of for someone to sell a lot of a product and have no experience with the product you should know this.
