Kick *** MRL 440

These heads were not maxed out yet either. They can be taken out to Max Wedge size, and with a 2.25" intake valve I dont see why they shouldn't flow somewhere in the 380's.

This engine has more left in it. With a Victor intake and a 1050, about 8* more duration and .050" more lift on the cam, I bet it would hit 700HP.
