I scavenge up all those "junk" low-compression heads my friends throw away, and then beat them at the race track with their own junk! A .100" angle-mill job and a set of big valves turns it into a 60CC high-compression head that will run rings around their high-dollar "Camel Hump" heads! The nice part is, they still have the low compression casting numbers, and most tech inspectors aren't sharp enough to spot the angle-mill job! Great for "claimer" engines that look stock!
