Is there a difference between the 4.0 and the 4.6 combustion chamber sizes?
I guess what I am asking, is can the heads be interchanged? If I find that my 4.0 heads are bad, I would like to slap on a set of 4.6 heads with the vin "9" cams for the extra hp. If the combustion chamber is larger, though, and they still fit, I would lose compression, wouldnt I?
