I can get a set of low mile take off ZZ4 heads pretty cheap. What kind of numbers do they flow stock? I would probably just do a little bowl work and gasket match since these would be "untill I could afford better" heads. The motor is a 350 and I`ll be swapping in a Isky 280 mega pretty soon. Thanks.

Bowl work and gasket match puts them in the 230 cfm range if memory serves. Decen't street heads in that form.

Mike, what kind of numbers have you gotten from the ZZ4 heads?

I'll have to do some digging. I think big valves and heavy porting would get them close to 300 cfm. I'll see if I can find my info.
