who to trust for hydraulic flat lifters these days?

I saw one of his videos a while back, where he said they had stopped regrinding cams and resurfacing lifters. The whole flat tappet cam and lifter debacle was taking so much shop time that they weren't keeping up with their other work like they needed to. I've heard they are a good shop. Especially to be in Iva, SC. That's barely a wide place in the road!
He seems to be very knowledgeable and experienced. I need to take a road trip up there one day.
