They don't oil the rollers too well when the engine is cold. The oil hole for the roller end is on the shaft area of the rocker. I had problems burning up rollers until I did the following upon Mike Landy's advice:
Cut a groove in the #4 cam journal to provide full time oil to the rocker gear; use 10w40 or 5w30 oil so it thins out faster. Plus I did my own modification to the rockers by using a die grinder to cut a banana shape in the bushing so the oil hole is getting oil through most of the rockers arc. That solved the problem.
Below is a pic of my engine running with the valve cover off before the modifications. This is after 5 minutes of warming up the engine, and the oil is warming up and starting to squirt. When it is cold, it just droobles out and does not squirt. You can see the squirt of oil, not really aimed at the roller. Landy told me that it needs to bounce off the valve cover and back onto the roller.

I see you have collars rather than springs too.....Why? Are collars better than springs? I've never seen these collars for sale, where to get them?
Take care,
