Two quick questions for you guys, probably common knowledge, but a search yielded nothing for me.

First, from my understanding of Ford modular engines, the 2004-2008 F150s with the 4.6L 2V should already have the PI heads correct? Way I gathered all 4.6L 2Vs from '99 and up should have the PI heads already.

Second, my motor's a Romeo, this should mean the only differences between my engine and the 4.6L 2Vs found in 'Vics and Mustangs should be the intake manifold and the headers correct?

Thanks in advance!

 

Yes you have the PI heads.
The truck intake maniflods are different than the cars.
I'm not going to lie about any other differences...

 

Thanks for confirming that for me
