I was dumb and didn't measure before sending my cams out so I don't know how much BimmerHeads took off.

Since my s52 cams are currently out I figured it would be an easy upgrade. Seeing a prolific tuner claim that the HLAs can adjust for the material removed from the base circle is obviously concerning!
Thoughts?

I've been told by a couple reputable cam dudes that these cams don't take well to regrinds because they can't get a decent weld on account of being hollow. Maybe some Eddy current/Faraday nonsense?
Despite that, (years ago) I installed a set of regrinds that were based on then unavailable sunbelt race cams on an S52. The vanos had to be shimmed and I think the springs and retainers were swapped out. With a custom tune and turned up to 7200(iirc) it made 292 rwhp on a dynojet.
Once race later upon inspection, the cam lobes were starting to wipe. womp womp.
