I hang out with alot of ford know-it-alls. I own a 97 2wd witha 4.6. They always say that a different set of heads could liven it up. tHEY must be the three valve heads on the later models. Is this the case? thanks

probably talking about the PI heads that the stangs use. Patriot performance makes ported heads for the cars and trucks. Flow real well and make good numbers.

PI heads are on all the modular 4.6 motors after like 2000

yea i knew i didnt have the good heads, iv heard of p.i. heads but didnt know they could go on my truck appreciate it

You are correct they are not on the 97.. Putting PI heads on is prolly good for at least 20.

on the newer 4.6 what kind of hp are the stock heads good up to? by newer i mean 06 to 08.
