The rockers isnt blue, they looks just great 
I have looked at this pump, what do you think about this pump?

Its a Anti-cavatation design pump, but it says "Using this oil pump will reduce pressure at idle"
Is it any problem to drive this pump on the street with the reduced idle oil pressure? |
Anti-cavitation grooves did not reduce your idle oil pressure too much in your current pump, did they?
I would not be surprised to find that the relief spring in your current pump has been clipped to reduce the oil pressure.
You could probably just call Melling and ask them to send you the high pressure relief spring for an M-77HV, and just put that in the pump you have now.
The weight of the oil had nothing to do with the pushrods going through the rockers if the rockers did not turn blue.
You can run whatever oil you want, but as a customer once said, "I wouldn't pour Quaker State on a rusty plow".
