DOHC Head options for 5.4, educate me please!!

Well, the way I see it, you have four options:

99,01 Cobra head: Optimized for a n/a 4.6L application, it features well matched intake and exhaust ports.

Navigator head: Similar to the 99,01 cobra, the intake port is visably larger to feed the additional cubes of the 5.4L.

03 Cobra/Mach 1/Aviator/Marauder head: Again, similar to the 99,01 cobra. The exhaust port is much larger when compared to the two heads above.

FR500: I don't have a freaking clue. For the price though, it doesn't seem worth it.

If you were going to stay n/a, the navigator heads would be the easy answer, but since you're using a turbo I'd say the 03 cobra heads are worth a look. I should mention that Modular Performance has a 5.4L intake for the navigator heads, but no easy solution is available for any of the other choices.

yeah

go steal a cobra r and use that intake..

i think most people use the navigator heads on 5.4 setups
www.modularperformance.com has an intake for you
