I think theyre about 64-65 CC's IIRC

TBI 350 engines are around 8.5/1 or 9/1 compression ratio which would put the heads at the 72 to 76 range.

I think you would be better off going with Vortecs.

I agree with this. 350 TBI engines are low compression engines. 64CC is for high compression engines.

Seems like 350 TBI's are 76, and 305 TBI's are 58cc.

Perhaps Scott would know.

If the heads are going on a Blazer or 1/2 ton truck go with the 67cc Iron eagles. They will give you very close to the stock compression ratio of 9.2 to one. Plus Just about as much power as vortecs without all the hassle.
Stock 350 2 bolt main TBI 1/2 ton trucks & car have 193 heads which are 64cc chambers.
4 bolt main 350 TBI 3 /4 ton and up trucks have the 191 heads which are 76cc chambers and 8.2 to 1 CR.
