My machinist only had to take .003 off my 66 440 block to square it and zero deck it . My 505/4.350 pistons came out dead flush even w/ the block , used a .039 cometic , 4.380 bore head gasket , guess what , I got .039 quench , !! Wouldn`t have it any other way , despite what arguments are made by those smarter than I am !!
