my pretty heads

Those look really nice. Really like those rockers and that port flow.

Did you take them to a machine shop to double check their work? I purchased a set of assembled RHS heads and they needed 3 new valve guides. The other 13 were good but those 3 guides were "barrel shaped"
Just my 2 cents.

He just had them CNC ported along with the valve job from Hughes...that is a machine shop...
