If it’s the same one that does cylinder heads from around Dallas, I would stay far away. Have a friend that ordered magnum cylinder heads from an eBay refurb shop in Dallas and checked them out. One set didn’t even have stem seals installed and neither would hold washer fluid past the valves. The guides were still oval. I’m amazed he was able to send them back for an immediate refund. I would be surprised if they ground a cam and it were still good enough to use for a decent core for a real cam grinder.
