I am aware they are a different alloy, but what about valves, springs, flow, etc. Thanks!


The hellcat heads don't interchange, the intake manifold bolt pattern is different to mount the supercharger.

look at this picture from a hellcat supercharger on ebay

I save the pictures before they disappear. It does look like you could have the intake bolt pattern drilled to match the eagle/apache/6.1L heads since the bosses are cast into the head but undrilled.
