Built this in 04 and cant find ALL the info, but I do remember have a couple tid bits.
-Heads bought bare, took to Jim Valako. In Grand Rapids MI, delivered valve sizes with Ferrea's. I believe he said that was all he could find at the time. But being a chev. guy, maybe did not know where to look.
Said he laid back short turn a little, and touched chamber, thats it aside from grinding seats,valves etc.
Rest of engine as follows;
