I also have a 302 Military GMC the suggested build for the engine is a .030 over bore clifford performance has a blueprint for that build I just got heads back from engine shop installed 1.94 intake valves and sealed exhaust seats new 1.5" exhaust valves my question is the timing cover is pushed in at crank seal does anyone have a better cover or can someone repair this one ??? and who will chrome plate the rocker arm shafts and bush the rocker arms so they are higher ratio then stock ? is there aftermarket rocker arms that will fit the shafts?
