I have 'em. What size? I assume you're asking about the combustion chamber volume? I believe they were 64.3cc to start with. This is 3ccs less than LS1 heads which would raise the compression ratio to about 10.8:1.

What else do you want to know?

Ls1 346 SS, i would consider ls6 heads if you dont want to port ls1 heads. Based on flow numbers they would pick up basicly stock motor nicely and would also respond to bigger cams. Compression bump would help power and un ported, the velocity to flow ratio should work fine for most combos. IMO
