I am looking for a cheap way to do something about my restrictive stock heads heads. I am debating buying a used set and trying to open and smooth out exhaust ports at home with a Dremel. What would be a good set to look for? I hear about Explorer heads. What year car should I look for or casting number? What else would I need to do? Probably a 3 angle valve job and decking or something? Any rocker recommendations? Would they help? Any ideas or help would be great.
