I just toasted the heads on the Lightning. Since it's basically the same motor as the 4.6 could I use these heads I found on E-Bay? Supposedly bigger stainless steel valves.

Here's a shot of the valves/combustion chamber if it helps.

 

Those are not 4.6 heads. Was this a trick question?

 

Silly woman.

 

The heads are 100% the same. They are PI heads.

They are correct in saying those are not mod heads.

 

What? those heads are not for a 4.6 or 5.4 ford modular engine.

(I just wanted to ask a Mitch-style question and see what people said.)

 

LOL I win!
