Ive often been confused by this issue, and I do wonder at times if it could partially be the type/brand of bearings used?

I say this because like 15-18 years ago I bought a couple cases of the MP cam bearings so thats all I use.

I have a simple cam bearing installer, take my time and in approx 35 builds have had one cam that was tight and it was the cam, not the bearings.

As for the 95% in, I have had a couple want to go past turning with my fingers but when I put the tiny ratchet on the cam bolt and spun it a few revolutions with lube of course it quickly freed up and I never worried past that because cast core cams will flex a good bit with real heavy springs so throught the running/thrashing process I think they at times run tight on the bearings unlike a rod or main.

So VinnyD, after it gets tight (do you mean finger tight) can you use a small end wrench on the cam bolt and see if it loosens up enough before you jump through hoops?
