They were ported by modern cylinder head in illinois. The board member that I got them from used them on his class winning car at last years hotrod drag week.
Unfortunately I don't have a phisical flow sheet. The numbers are from a link the origional owner sent me. If that becomes a problem I can have them flowed locally, but the price will go up 50 bucks. I can post pics of the port work if that helps.
Not really looking for trades, but what did you have in mind?

camarojokester, I'm not real sure if these will work on a stock 5.7 shortblock. I was told they would work fine on a 4" bore the intake valves are 2.08" not sure if they will clear the bore. I will measure the chamber and post up. thanks,
Kory

I had these flowed at the local speedshop. here is what they flowed
intake exhaust w/ pipe
.100 68.5 53.9
.200 147.4 102.9
.300 212.1 144.5
.400 271.6 184.2 195.5
.500 308.7 218.5 228.5

.700 332.6 232.7 250.5
The intake numbers were very close, the exhaust numbers were off a bit. might have been a different size pipe than was origionally used.
