I have a 350 that I am about to put vortec heads on. The motor has flattop pistons with 4 valve reliefs and has a stock deck height. I have the intake and all the necessary hardware for the swap. I plan on driving it as a daily driver so I want to use pump gas if I can get by. So my question is do I get the head gasket with the .041 compressed thickness or the .051 thickness. According to a compression calculator, the final ratio would be 9.96 or 9.71 respectively. Am I splitting hairs here or would one gasket give me a more desireable quench than the other? Thanks.
