I just bought a NASTY set of heads. The CASTINGS ARE NEW AND 1 OF A KIND FOR Z06 EXTENSIVE CNC WORK, RAISED RUNNER 2.05 X 160 VALVE SIZE, CUSTOM EPOXY WORK, 232 INTAKE RUNNERS, CAST # 243. THESE HEADS HAVE STAGE 4 PORTING. T.E.A. BUILT THESE HEADS TO GO ON THE OWNERS CAR. SEATS AND GUIDES ARE INSTALLED, 72 CC CHAMBERS FOR A 3.900 BORE, LSX OR WEIAND INTAKES ARE COMPATIBLE WITH THESE HEADS. EXHAUST CC IS 287 EXHAUST FLOWS. INTAKE FLOW # ARE ..700 LIFT 346.3 .600-- 341.4 .500-- 306.5 .300---208.6.. I have no flow sheet to back this data up, but it is the information that I was given. They are bare castings and will still require valves and valve springs. They're BRAND NEW.

I have decided to go a different route..They're tooo much for me. So no need for them.. $1600 takes it...

those heads did not flow close to that number.

 

That's just the info I got from the guy I bought them from.. My apologies to everyone then.. New price of $1100..

 

Brent,

looking at the TEA site, the "stage 3" LS6 heads are said to flow 340cfm at 0.600" lift; why wouldn't these flow in that range as well?

(simply trying to learn)

 

It's probably because the compression ratio is lower for FI cars.

 

those heads will not flow that number on a 3.9 inch bore. The numbers on TEA's website are for a 4.125 bore.
The guy that originally bought the heads misrepresented them on Ebay. I have told at least one owner the truth about them. They will be killer in a forced induction engine. But for a N/A engine I doubt they be worth to much if any gains.
