360 Mild Build Questions

The word mild is the key take away here. As far as the worst offender I've seen on a factory 360 was a 1972 Windsor foundry casting with 587 heads with a -7 on one side and a -12 on the other side. There was an average of 5 cc's of difference in chamber colume from one head to the other. If you could find some 974 heads, have the chambers equalized, and install 1.94/1.60 stainless valves with a four angle valve job and clean up the rough edges in the bowls and ports (most an be removed with emery cloth roll) you would have one of the better iron heads available. The 318/360 performer intake will work well if you do a deep port match on it.
