Lifter blocks

Lifter blocks were a perfect in my 1990 FLSTC Evo block and Feuling lifters. Only issue is the machined counter bore that the lifter tube fits into with the spacer and o-ring is a shallower cut than the original blocks. Initial startup developed oil leaks but I coated the o-rings with lithium grease and they sealed up. Measure before installing them.
