hydraulic roller lifters issues

Are you having this issue with the Hughes lifters, or are you considering getting them to fix the problem? I think MRL also has lifters with the oil ring lowered just for the uneven lifter bore heights in in small blocks. I would get the lifters before having the cam reground. At least that way, you can sell the other lifters and recoup part of your money.

I got the Hughes lifters to fix he problem and all bores are good except one. The oil ring on the lifter peeks out less than 030 and after measuring the cam the base circle is 060 bigger than the barrel so I should be able to take 040 off the base circle. That will give me a margin of error of at least 010 and leave the base circle 010 bigger than the barrel. Rather than do just the one lobe I thought I will do them all, That way push rods will all be the same. Does that make sense?
