I found a set of 243's with an LS6 intake for 850$. The heads are complete and both the heads/intake only have 4000 miles on them. They look brand new. Is the price fair? Forgot to add, they have the sodium filled valves and come with valve covers too. Thanks in advance.

Thats about the going rate. Its not a smokin deal but you wont be gettin hurt giving that much for them.
#317's and #799 are the same heads for a cheaper price the #317 you will have to spend 50-100 getting milled the #799 is the same as #243 and i paid 350 for mine ls6 goes for 250-350

I NEED A FAST INTAKE PM ME IF YOU HAVE ONE FOR SALE
I paid $500 plus shipping for my 243 heads off an LS2 from here assembled. I sold them for the same amount when I bought the complete LS6 engine. LS6 heads, what you're looking at, aren't worth more than the LS2 heads because it is debatable that the slightly lighter -- and thus slightly weaker -- valves are "better." For what I want them for, a street car, the LS6 heads are a little bit better, but a high hp engine is going to replace them anyway. So, they're all worth the same amount in the end.
I think $650 shipped is the going rate, IIRC, with $500 plus shipping being the good deal around here.

Thanks. I'm gonna offer him 775 and see what he says. 799 casting are the same as 243? I've seen the intakes go for 350$ used so I think I'll be doin alright if he takes that.

I actually would prefer the solid valves because that way if there ever is piston to valve contact it will only bend the valve, not break it and destroy the motor completely.
More than I'd ever pay for that setup.. but I always try to find the best deals then turn around and make a profit..lol
I bought some LOW MILE (2k) LS2 243 heads for $200 and resold them on here for $450. Also some 799 heads for $120 and resold them for $350.
You could save at least ~$100 by buying that stuff separately on here or find a local deal.

The way you typed that with no punctuation or grammar makes it seem very confusing..hah
Edit: Oops I just realized you're the one who bought my 799s..haha.

Funny, I have been doing the same thing for a while. I make around 100$ a week from buying the cheaper stuff on craigslist and selling it on Ebay. Where the hell did you find 243's for 200$?
I bought a set of 243's from a local guy. They came off a 10,000 mile 2002 Z06. Paid $350 for them. There are some good deals out there, you just need to jump on them when they come up. That's not too bad of a deal for the heads, intake and valve covers, but i would offer less than that.
The 317s are truck heads and will lower the compression ratio to about 9-1. They are popular for forced injection motors. That is why it is recomended to mill them down to increase compression, something not necessary with 243 heads.
Two, the LS6 heads have additional features other than the lighter sodium valves and better springs for higher RPMs. The heads, if genuine LS6 products, are also CNCd machined and flow better than the standard 243 heads found on LS2 motors. I do not have the charts in front of me, but I think LS2 heads flow at 260 CFM on the intake, while the LS6 heads are about 280. This figure volume matches the LS6 manifold which is rated the same.
The 799s are found on 4.8 and 5.3 motors. They have the same size valves and almost identical chambers as the 243s. They are a good choice and can be found cheaper than 243s which have the reputation. They can be ported and polished to make over 300 CFM at 600 lift, but they come with standard stainless steel valves. They flow 260ish stock. Hope this helps.

Thanks for all the advice. This is my 4th LS1 car, but my first time ever looking to change the heads out so I am somewhat in the dark. I certainly want to pay a fair price and get something that works for me. My car is a 2000 WS6 6 Speed with a FIPK, Full exhaust, TB, Hotchkis spings and KONI shocks and 373's(Z06 Clutch and Slave/master also). I'm going to do the heads and cam here in the next two weeks (and get some sort of aftermarket intake or an LS6) I'm just wanting to break the 400 WHP mark.
Personally I think thats a good deal. Don't forget the valves, they offer a lot of advantages for valve train design. Just don't go with monter springs.

243 Heads price fair?
