well stock heads can only do so much, but i would change the valve springs at least
so you dont end w/ valve float, but you'll have a much better gain w/ aftermarket heads

302 parts will make 302 power. you should put some heads on that thing.

you will see a much bigger benefit than swapping the cam.

I agree w/ the above about the heads and valve springs, but also look at the TFS stage 1 cam. I have the E cam now, but I'd have gone a different route if I'd researched it more.

If you still have speed density its no going to like a cam being put it.
