I have a question. I know the heads on a 4.7L engine will fit 1999 through 2007. But does anyone know the differance in the heads? I have a 2007 Ram 1500 with a 4.7L engine. I am needing to know what all to do with a 2000 year set of heads to make them work? Such as cam, sensors & such

 

I do believe the egr valve is located in the back port on the 2007 heads not sure on the 2002.

 

Sensors may change to match harnesses over the years, just use yours. EGR is on the back of the head on those things. Basically same head through 07. Only power rating difference during those years was the HO cams in the Grand Cherokee.
