Hey all, I have a 2006 f150 with the 4.6l romeo engine. I just got the truck and the guy said it needed a tune up. Well, it needs a couple new exhaust valves instead. So I looked on here and other forums to see what 4.6l will work. Some said any. I bought a 4.6l romeo out of a 98 f150 with 75,000 mikes on it. Thought I did good, now I'm reading about pi and non pi heads so my current intake manifold and cop's will not work on this engine. Is this true? Or will my 06 intake manifold bolt up and work fine. Thank you all for your time.
