nope. 4.6/5.4 2v heads are pretty much the same, no advantages to either one. there is not an aftermarket company that is making their own casting as of yet either.

Like sweet said there is no aftermarket casting for our heads....but that does not mean that our stock head setup is the only option out there. You can have your heads ported and polished, or buy heads from a company that have gone through and ported and polished. Cams will also wake up the air flow quite a bit. Read around in the forums, you will see all of this discussed numerous times.

.500 wat? lift? your PI cams have .530 lift
BUt PTV isnt from lift ethier. Its all from a combination of lift, and duration... the longer the valve stays open the more chance that the piston could hit the valve.
