    I'm building a 302 to go in my 1965 mustang and I want to put a set of gt40 heads on it. I read that the gt40s have some issues with long tubes which is something else I'd like to have.

    I recently bought some GT40P heads without pushrods off Ebay and I bought new hardened pushrods for them also. How do I install them? If I understand it right, I need to check piston to valve clearance. Do I need to crank it over until each piston raises and tighten down individually? If so...
