Re: difference between z6 and y8 head (shorty91)
first thing...search.
the z6 head is circular cumbustion and the y8 is squared off. the y8 on a z6 bottom end will pull better #'s.

Actually the z6 head flows better. Zex Man from the D series bored put down 40 more whp in the top end with the z6 head compared to the y8. This is extreame ammounts of horsepower, but he lost that because of the sqaure combustion chambers in the y8 head.
