Question 1998 GT 5.4 Ford lightning head swap?

I have a 98 gt and i found some heads off a ford f-150 harley davidson edition with the supercharged 5.4. i was wondering if these heads would work on my 4.6 2v? also could i use the p.i manifold? and what would have to be moved? thanks

if the head off the f 150 is a 2 valve it should work i believe. the new trick flow heads for 2 valves are the same head that can go on both the 4.6 and 5.4 so im just guess that they would though maybe someone eles can give u a little more info... i think the only problum u might run into is the coolant flow make sure they meet up in the right places

They are the exact same head as the 4.6 PI head.

Yes, 5.4 heads and 4.6 heads are identical. Both of your vehicles have the same NPI heads on them.

What correction? I know for a fact that the Lightning/Harley Edition 2V heads are the exact same heads as what's on a PI GT. There are minor differences between the Romeo and Windsor heads, but those are readily known.

My correction is more of a point.... The corresponding intakes need to be used because the gasket flange is unique.

Just needed to check where I wrote down the differences and commented to remember to do just that later in the day.

He'll just have to get the intake and gaskets for the 4.6 PI Mustang along with the coolant tube, there's nothing special involved, it's a standard PI swap.

A typical PI headswap with all the trimmings adds about 50rwhp. It all depends on who ported the heads as to what gain that adds, home/amateur/non-4.6 guy ported heads typically don't perform as well as stock, while heads from Patriot, Fox Lake, MHS, etc are worth 20-30rwhp.
