who is running MRL (BAM) Lifters without lifter bore sleeves

It may be a case of the bores are worn too. Seems like there might be something else though - an HV pump with those clearances, even with a few "extra bleeds" should have plenty, especially with that oil choice. Have you tried just swapping the oil pump?
I ran this motor before with a more stock build oil pressure good.
I thought about the pump
So I just went out and started the motor cold 45 at idle so up to 65 revving the motor, it will go higher (buts cold did not want to that) from before when it worms up it drops.
