I agree with a previous poster. The blueing on your pushrods isn't from starting it after sitting a long time, it's from lack of proper oiling and the resultant heat. Probably took running it a while to get like that. Nothing is hot in a cold motor, and oil will get upstairs extremely quick, definately isn't the issue you are seeing.
If I were buying new rocker gear, without question I would( and have)use Jesel. They make a setup for W2/W5 Indy stuff. I ran a set trouble free for years. The best out there.
