wideopen231friction coatings
First I am not looking for performance gains. Looking for durablity.
Amyome here tried any of the friction reducing coatings? If so which and for what part?
I am looking for something that will holdup on adjusters and pushrod cups. While not a probelm for most here. On Hemi's the oiling systems do not feed oil thru pushrods,but rely on oil that is fed threw rocker standsto shafts and out holes under rockers. When rocker hole aligns with oil grove in shaft it gets a very short squirt.How long does a 1.8 hole align with a greove that is about 3/16 at 8000 rpm? Not long is answer you are looking for.
Have contacted few coating company's, but no responses yet.

wideopen231Shafts never had issue.Even in TA/D where shifts where 10500 and leave was 7000. Right now price little bit of issue.700 bucks to do enough piece for 2 motors.Heck the piece didn't cost that. Hoping to find cpl other to go in on minimum order.
