question for neal
Hi Neal... I have been reading with much interest about putting 5.4 heads on a 4.6. I have a 2001 f150 4.6, My question is will this work for my truck, are the heads a direct bolt on?, are the 5.4 PI head cams the same?, should i use headers or will stock exhaust manifolds work?, are the stock injectors enough?, and most important how much horsepower will i gain?. thanks in advance Larry.

Speeder, I can't answer your question. But Neal is currently off-line for a couple weeks 
so you will have to wait for his return unless he uses a friends internet time.
