Do 6.4 heads bolt on to 5.7 blocks? Or will the bore size shroud the valve? (hopefully I am saying that right)....

Also, do they use all the same rocker gear as say an early 5.7, so that it can all just transfer over to the 5.7 head?



Matthew I place one of my Apache heads on a stock bore 5.7 without a gasket. I even posted a picture here on Moparts. But for the life of me I can't find the post LOL

Anyways they do "fit" you would have to notch the top of the bore, IMO nothing major.
The real question is . Is the Apache head TOO BIG for the bore limited block? :twocents
