yes i have the stock heads on it, for now anyways. with the factory pulley i was seeing 5 psi, now with the f150 pulley i see 9 psi. big h.p. increase for $20 huh. i took the fmu off because it is a 14:1 and at 9 psi i was getting way too much fuel. i put a mallory regulator on it now. it is boost sensitive, like a 1:1 ratio. this helped out big time. i would like to get a different fmu around the 4:1 or 5:1 just to keep it alittle safe on top end. never know though i could be ok now with the way it is. going to go to the track this thursday night. my first run i'm going to pull a plug and see what it looks like, hopefully be ok the way it is right now and not have to go with anything else.
