Will this bore clean up, magnum head content too.

ok, anyone know of an LA cam that has .464/.447 lift Int/Exh ???
that's a weird one. maybe i should measure a few more lobes. I measured off the lobes through the hole right above the cam.

I found an Elgin cam, 936PK that .444/.466 lifts but the Int and Exh are reversed to what I measured. I double checked the lobes i measured.

Are you 100% SURE you got the intake and exhaust lobes oriented right? I've made that mistake a few times myself. It's easy to do. I cannot think of a single flat tappet that's a reverse grind off the shelf. That would be very strange. Did you try another pair of lobes to duplicate it?
