i have a 97 f150 w 5.4L
any other 5.4L motors that have a higher flow head that i can swap out? or maybe switch the 2 v for 3 v? thanks

 

a set of 2v pi patriot 100% cnc ported head run about 1295-1595$ dont forget the pi intake also.

 

should i use the stock cams also or ungrade? and which one? doing mostly hwy towing w 16 ft enclosed.

 

call comp cams and see what they suggest.i would also find out the lift specs from patriot to make sure they will work

 

If you get those Patriot heads, go ahead and get 2-3 sets of gaskets and headbolts. You'll need to pull them back off 2-3 times and send them back in before they possibly get them right. Broken valveguides, broken valveheads, and excessive oil consumption from improper sized guides is the norm for that garbage.

where are u hearing about these kind of issues.id like to read up on them.

 

Use Google-it's all over the internet.
Supposedly, all of their "issues" are fixed. They supposedly had a poor quality valve guide supplier,and also cut the guides flush with the port walls to get more flow. This makes the valve flop around in the guide and use gobs of oil when the seal gets chewed up. I wouldn't touch them,and if somebody tried to give me a set of those garbage heads-I'd not so politely tell them where they could stuff them.

wow, sounds scary running those heads... anyone on here using them??

so, no trick-flo or edelbrock heads for 5.4L? what about the lightning heads?? would that be more efficiant?

 

Lightning heads are identical in every way to any other PI head that's on every other 2V 5.4L from '99-04. There's nothing special about them at all.
