Cam Bearing Advice

I do the same. Been doing that since I was a kid workin in a machine shop whan I was still in school. It was owned by an old retired Navy machinist. He showed me how to do it. Works great every time.

We have modern tools now. The old ways are doable until you start running roller cam spring pressures and coated cam bearings. Alot of folks including myself used the slittes cam method and scraped bearings for years. We know better in 2025. My 499" intake springs are 300/870psi. I'm not scraping the coating off of the bearings. The proper way to correct the issue is correcting the journal bores to get correct crush on the bearing.

Because....math and science : D
