True I used the Indy head for that article...I work with both heads almost everyday, biggest difference is the short turn height on the EQ head is taller than the Indy...My cnc port fit's in both heads, so they end up flowing the same on the intake side, chamber is damn near identical, and ex. port is very good on both heads. So power should be comparable but I have never done a max effort deal with the EQ head...this would make a very good test! I still have the 393 short block just as it ran with the Indy heads. Might have to look into this further with Eric. I would also love to test different intakes against the Indy just to see where they end up.
