Ok with all the head flow numbers floating around what is the opinion on the best head to use. I have a 6.1 block but no heads. I am building a 4.080x4.080 stroker custom JE pistons shooting for 13.1 + compression with the goal of 750+ HP. This will be a carbureted setup with a Ritter intake I have the intake already. Starting from scratch on the heads what does everyone think ??
