Re: 302 rebuild
GT40 heads would be great for a budget. If you get the cobra rocker arms with the heads I would leave the cam alone, if you dont get the rockers go with a 1.6 ratio and get the ford motorsport E303 cam. It has a slightly more aggressive idle, I had the GT40p's with some valve and port work and they did awesome. The 40p's are a better head than the 40 but less user friendly, so I would go with the GT40s. But you are on the right page for a budget build. they dont have to be aluminum heads either, they are nice to save weight but they flow the same.
