Ive heard that the Patriot Heads SUCK. If I were to spend the money, Id go with Tim over at
www.modularfordpowerhouse.com He is an amazing guy and his customer service is UNMATCHED. He got patriot heads that a customer wanted to put on a car, and he said that the valve guys were loose and that he wouldnt recommend them to anyone. Those heads are also truck heads, from what I hear. And the VT cams are also some of the most popular, just watch out for PTV contact.
