Dwayne, I will say Hughes tells me that's not an issue due to lifter only being there for a short time period..... I'm not buying that, what say you????
I have the same lifters .610 lift had one in #3 doing the same, swapped some lifters around & it was a LITTLE better but still blowing out oil. been running it this way about 4k street strip miles, I do have HV pump, stock rocker oiling AND pushrod oiling. still in the back of my mind I wish I would have had the block bushed, but so far no problem, really I wish I had just gone with a good aftermarket block.
