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?
