RHS Indy 360 X Cylinder Heads

I'm running a set of the MA-X, these heads flow pretty good OOTB, i got mine from Hughes for 875.00 complete, in stock form they'll support 450 hp, even with my very mild 360 magnum, its a screamer, & i'm only running a 2.76 gear & stock converter. They are well worth the $$$.
