1.6 Rocker Arm Install , Lube questions

#7 needle bearings were starting to dig into the hardened shaft. New shaft being installed. I will probably run these for a year or so and then convert to bushed rockers. The 1.6 ratio is a test.View attachment 1715822742

That’s one problem with needle bearings on a shaft. The shaft has to be harder than the hubs of hell or that’s what you get.
