does anyone know about the patriot perfromance heads for a 4v 4.6l? its a mach 1. it says like 1400 for stage 2 heads with no exchange required or something liek that, that sounds kind cheap, r they nice heads or just crap?

you dont get new heads...you send them your heads and they do their own job on them

actually, i think you can do it either way......send 'em yours, or just buy a new set. Muscle Mustang & Fast Fords did a test on them, and said they were worth the $$ w/ a good increase in hp and torque all the way across the board
