So I got a steal of a deal on an 07 dakota with the HO 4.7 from an auction, the heads were gone but the rest of the motor looks like new sitting in there, even the guides and chains look awesome but the intake and whole top end is gone. I found an 02 top end complete for real cheap, can I just bolt it all on and make it work? The interchange at the JY says only one head will swap, what could possibly be different? The truck does not have EGR. The intake is supposedly better from reading on the line but can't find any details of would keep me from useing the 02 intake even though the interchange says no way.
