So I did a search but I really couldn't find anything concrete. I don't know much at all about 4V heads as of yet but I have been doing a ton of reading and I'm unclear on a lot of it.
I am going to build a 5.4 4V swap for my 99 GT. I will be using a 99 Navigator block. From what I've been reading that ported B heads are best for boosted applications due to them not overshooting the valves. Will there be problems running the B heads with the Sullivan 5.4 intake manifold? the B heads are made for 16 runner intake manifolds correct?
Would the 03+ Navi heads outperform a non ported B head?
I know that 4V heads will perform better than any aftermarket 2V heads stock so I will probably be running an OEM setup just don't know what the best stock cam combo will be best.
I was thinking of running the Navigator intake cams and Termi exhaust cams in the Navi heads.
Anyways just looking for some insight here. thank you all... and I look forward to moving into the 4V forum lol.
