Any 99-01 or 03-04 cobra. Also the aviator

Direct swap or slight mod needed?

[bolsen]

Should be a direct swap. You can get Cobra Highflow Heads. Supposedly add up to 30hp ($2000).

Are the Cobra Highflow Heads a Ford item or aftermarket bolt on?

They list the price at $3000. Are they available elsewhere for 2k?

Anyone know if the new 5.0 4v heads would work?

[dohc324ci]

Our heads are exactly the same as the 03/04 cobra/mach i heads. Just port your heads and a nice set of 98 cobra cams. The only one i would consider doing is the Ford GT heads cause they flow more but will set you back $3k.

Negatory on the 5.0 heads total redesign.

Navigator heads have fitment issues, they'll bolt on but the intake manifold will not fit in between the heads. Also, the Navi intake ports are too large for a 4.6; low velocity and also low cfm flow.


Do you mean 99-01 cobra heads ?
4V hads that bolt on without mods:
-Any 99/01 4v head
-heads from 03/04 Aviators, Mach 1s and of course Cobras

The intake manifold is going to be the constraint to making power on any n/a combo. You can have heads that'll flow 350cfm but they'll produce little power over staock heads because of the intake.


A simple valve job, bowl port and cleanup will provide about 90% of the gains a set of $3000 heads can get ya.
