A balance between being too rough and too fine, he says if the wheel is dressed to give a perfect finish it burns the surfaces and causes micro cracks. Says it will all smooth out perfectly when run in with some moly grease applied to lobes and lifter faces

Well I guess I respectfully disagree there. Good to know what their take on it is though...

@BobbyBreeze any idea what sort of vacuum I should be getting at idle with a pretty mild cam? The fresh engine is sitting at about 65 kPa absolute at idle (10 " mercury pulled), with stock cam I was at about 35 kPa (19 " mercury pulled)

 

I'd say around 16-17" Hg with a mild cam. Generally stock nanna engines are ~20" Hg, Hot street engines 13-14" and full race 10". Any chance you have an intake leak anywhere?
