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

What u running for oil. Should be at least 15/40 or 20/50 with that clearances. Kim
brad penn brake in oil then change to straight 30 with good wix filter
I was going to dump it and try the 20/50 but was told wise time and money that I have a bleed off issue in my motor. That why I am thinking lifters
