holley heads > gt40x

GT-40x heads aren't thegreatest heads out there, but they are still good heads;better than the GT-40(p)s and are aluminum too meaning they are much lighter (about 25lbs lighter each).

I'm running gt-40x's too and they do put down some power. I got them really cheap thats why I got them
