I've pretty much given up on the idea of making a 4v out of my 2v 2002 5.4L F-150. The 4v would give me what I wanted to 3000 rpm and then kick in the other intake/exhaust runners after that. It seems the closest I can come is by using a set of 3v heads. Any body have an idea as to what would be involved? Comp Cams has the cams so it must be a popular enuff engine to consider making them. I would imagine the stock ECU could handle the new (ported) flow requirements. I'd appreciate any help I might get.

 

Navigator heads and intake will be your friend, Oil passage ways in the 3v head are different vs the 2v head for the VVT, Unless you do a long block swap VVT is not going to work.

 

I was only going long block if I was going 4v so all the parts would be there. I didn't want VVT any way. I just have to get a pair for core charge that Livernois Motor Sports charges. No core will cost an additional $800.
