    Only thing I can think of is Valve Lift causing Rockers hitting?

    I’m not sure what the reason is for the extra height. One thing I do know is that the plugs are going to be miserable to change!

    Could be to combat pressure from the super charger

    No Idea unless cosmetic to match up to the Supercharger?

    To create 800-HP, anything the Blower creates had BETTER stay in the combustion
    and not end up as blow-by. . . .

    Never gonna happen. Just think of the boost gauge on a supercharged engine. When you see that pressure, it would be near zero on a naturally aspirated engine. That’s a phenomenon that a standard PCV system doesn’t have to deal with.

    Yes, the Elephant Hemi looks better.

    But I wouldn't throw a Hellcat out of my garage. I don't care what the valve covers look like!
