I have given up on the 402. I have taken the 454 to the machine shop. I will be going with the 781 heads and am having 2.19 and 1.88 vales cut in. The speed pro pistons have a .210 dome and will give me 9.77 to 1. My crank will be polished and will use pat's recommendation for a roller cam and rockers. It will be a slow build as I have alot of truck work to do.
