On a stock '85 Vette they gave 11hp; 1.6:1s another few hp.
My 1.6RRs didn't show immediate gains due to a false knock issue.
Part of the gain comes from reduced friction, maybe part from exact dimensions and some from increased lift & duration (with 1.6s) if the engine needs more cam.
Check out the recent 1/4mi gains made by J.Panuzzo (Red96Coupe) by adding 1.6RRs.

the factory stamped steel parts are junk. the factory parts are inconsistant... they claim to be 1.5:1... yea, right...
they vary... anywhere from 1.4:1 to 1.55:1... and they can vary within cylinders!
this is bad...
