Who has done this and what company? I have several sets of hyd lifters (used 20-25 years old) Lunati/Isky that I would like to repurpose. A web search disclosed that Schneider Cams still performs this. However, this community has a plethora of experience for knowledge. Thank you!
Found this with a Google Search, https://egge.com/lifter-resurfacing/ http://schneidercams.com/Lifter_Resurfacing.aspx
This shop does lifter refacing: https://www.youtube.com/@powellmachineinc3179 I have never used his services, but I have watched many of his youtube videos, and he seems to be a knowledgeable machinist.
Unfortunately, Powell Machine no longer refaces lifters. In one of recent videos he said they sold the lifter refacing machine and they no longer offer this service.
