Lets get this straight, before every key board engine builder gets their pantie in a twist. First and foremost I F---Ked up plain and simple!!I had done the heads for a 396 and when we switched and made it a 402 I never gave the valves a thought. Till dave measured it ! Yes I f--ked up!This is the reason anything that goes 1.200 under should be torn down.Why should he (or other w/ comb) be hit if his was not legal? BO what if I were to put a different blower or pulley on, and wreck your combo? As far as the guys that call themselves engine builders and want to go around the track saying this and that, JUST maybe if you did your own stuff rather than having it trucked in, then maybe you too would make a mistake once in awhile! Yes I'm sure the big valve will slow it down probably will not be able to run the index
