This may or may not have been discussed before. I am only wondering if the heads on the 5.4 triton are interchangeable on a 2006 and 2008 motor.
I'm looking to, if I can, swap heads on a 2006 3v triton to solve the oil pressure problem for good on a motor that seized. Any advice will be helpful.

 

Yes 2008 heads fit on a 2006 motor but you really want the 09+ heads for all the updates.

 

So the 09+ will fit on the 06?
