QUESTION: HI MIKE, only taps loud hot, outside temp was 85 degrees, has an oil cooler,

Answer
Since you changed the lifters and that didnt help I would try adjusting the pushrods looser and let them pump up. If that doesnt solve the problem then you need to recheck your work. You may have a rocker the is too loose on the shaft.
Good luck and happy riding
Mike
