I did also. Since those days I have learned from my son about making the bores perfect. The performance gain is noticeable to all the customers tuners on the Dyno , also leak down is better then minimum. Most of the high dollar engine builds that he does the machine work on go on a dyno after built. 6 left yesterday to one race shop. and they dropped 6 more off. From what I heard in the shop but not positive a set of heads from you are going on a bottom end being done by Steve.
