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.

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.

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.
