That is hawt! I just got done porting my new head and it didn't turn out that nice. I'm curious about the dimples outboard of the valves, I take it that's factory on the X's for some reason?

Wondering if you have the numbers of what a stock head flows vs this ported one?

Can you do a overlay with the ported head with the graph and mods below?
