According to another post, 6.4 heads are made of the better aluminum alloy like the Hellcat heads. I have a set, so when I gat a chance i could test fit the blower and see.


I think the 6.2 heads are stronger aluminum.
As for the difference in blocks.


6.4 TRUCK heads only. Car 6.4 heads are 319 alloy vs hellcat and truck 6.4 356 aluminum alloy with T6 heat treat & age.

Also, you can't test fit much of anything with any set of 6.4 heads and a hellcat supercharger. The bolt pattern is completely different, as I stated above.
