Lifters are a pain. I am alsways on the hunt for them. At the trifive nationals, I picked up an NOS set of TRW 55-58 hydraulic ifters USA made in 87. First I have come across in a good many years. As for resurfacing, my vote would go to Rocker Arms Unlimited in California., Besides correct rebuilding of the chevy rocker arm assemblies, they also regrind and resurface lifters.
