Mancini Stainless Steel roller rockers

I actually varied the ratio on my PRW rockers. They were slightly over 1.6 under load (1.61 to be pick the pepper out of the fly poop) and with the B3 correction kit I lost all of about .008 lift from lobe lift thought the pushrods and rockers.

Pretty dang nice really.

Are yours for ball/cup pushrods or ball/ball?
