Alrighty guys new to the forum and new to completely rebuilding engines. I currently have a 6 cylinder 80' hatch and I wanna build a 302 for it. Here's where I'm caught I have a 72 302 out of my old f-100 I put a Cleveland in. Is there anything differenet about that year I should watch for. As well as what head should I be looking for? I already have a lunati cam and forged Pistons I can't figure out which head would be best gt-40 or older 351 heads ported out or cut to the chase and get a set of aluminum heads? Any one able to help me?
