Bought some heads online from a 2k saleen the part numbers match a 5.4 pickup what gives? will these work for the pi conversion and what bolt pattern will the valve covers be I count 12 bolts on top of head and 4 on the camgear side. will these work for the pi intakes the part number on the head is rfxl3e6090c20d pi

 

They are windsor heads and will bolt on fine but you will need to get new valve covers, your covers wont match up.

 

What year is the 5.4? Yes those are windsor heads but if truck is a romeo block you're gona have to chains the guides and chains. We had to do that on my buddys GT when he did windsor heads on a romeo block.
