I did the same thing. I bought 243's off ebay and sent em out to TEA for their Stage 2 with a 62cc, mine should be in any day now. I just got my cam from EPS too so I have to start buying the other swap goodies. I'm even more excited now that I see your numbers.
ive been researching like a **** since i became a member here on ls1tech and flow numbers i still don't understand.
.1000...67.0...56.9
.2000...137.6...123.0
.3000...216.0...181.6
.4000...269.2...233.7
.5000...308.7...256.6
.5500...321.4...262.3
.6000...327.5...265.2
i know the first numbers are lift the 2nd are intake and the 3rd are exhaust. i know 340-350cfm heads are great for ls1,ls2, and even ls3 blocks with 4.0" bore. i know 380cfm would be enough flow for and ls7 for great numbers.
i just don't understand what to look for or know what to go by as far as intake and exhaust in relation to the lift? can you guys shine some light for me please? i always research before askin questions but there is times when questions are need to be asked ya know. thanks fellas. judging by the cfm they're putting out for the money this is awesome.
what cam would be ideal for a nice midrange? an advanced cam with a few degrees? sorry for the write up guys

* update car ran a 11.85 with new TEA heads installed and a rough tune *
**Update : Just Changed out the PCM a few weeks after this run, from a 98 to a 02, Much better control over the WOT. After that upgrade she ran a 11.34 @ 120 3.90 with 28' tires.
The 98 PCM is what was throwing everything off.

wow...that is a low mph. I have a 224/230 cam with a vig 3200 in the car. I have the same stall, and heads waiting to be put in the car. Still have to get my cam that predator spec'd me ordered. 227/231 110+1. What does your car weigh, and what is your suspension setup like?
the 806 heads were stock nothing done.
its an auto trans with a 3.90 gear so the mph is on.
why what u think it should run?

Ok so my new cam is a 234/242 614/614 112 what stage TEA 243's would be good. I have 921 springs and the stock ZO6 valves/hollow sodium filled new. I just need to get the heads done. I am adding a 150 wet shot also. The shot is going to be set up in a two stage 50 shot out of the hole and then the 100 at around the 60 foot mark.
I would bet she weighs about 3900 with me in it. I have to scale it to see, but she is all stock with everything in it still. Spare tire and all. The air wasn't that great the day. I ran and it does have a rough tune in it. she also has shot slicks on her. She has got some room. that run was just her maiden voyage after the head install and rough tune. there is more to come. she inst final yet.
