I like the factory pump better than the cast iron aftermarket units. There is nothing wrong with measuring and inspecting a used pump. Its its still well within new specs there is no reason not to reuse it.

BTW.... I am going to do some measurments on what happens to your valve timing when putting roller rocker arms on a factory cam. I have a spare head and cam to test with, I just need some spare time.

I am not convinced that its the hot setup.
