dohc 5.4
As far as I know they don't exist. You may be able to throw the 4.6L DOHC heads on a 5.4L SOHC engine but you will have problems with valve to piston clearance beacuse the 5.4L is stroked relative to the 4.6L.

dohc 5.4
DOHC 5.4's have been out for at least three years now. The Lincoln Navigator comes standard with a 300HP DOHC 5.4. The Lightning uses a Supercharged DOHC 5.4 producing 380HP as does the new SVT Cobra. I'm sure you can find info somewhere about the DOHC. I'm not sure where myself but it must be out there somewhere.

Lightnings do not currently use the DOHC 4 valve heads. Corral.net has the 4 valve Navi motors COMPLETE for $3600. Pretty sure it'll fit in the Marauder.......that'll take care of that low end torque problem!!!
