    Here is an interesting HEMI head flow comparison between the 5.7 and 6.4.

    Interesting. The biggest advantage of the 6.4L heads over the 5.7L ones appears to be in the exhaust flow.

    Exhaust flow becomes more important in a supercharged engine, as you can see from the cam spec differences between a 6.2 Hellcat engine and a 6.4.
