Unless you deposited more metal on the lobes before regrinding, and didn't have adjustable lifters, you have a real problem don't you?

If you are thinking about getting it reground, DON'T. These engines have no camshaft bearings so any metal they remove will cause increased clearance with the engine block and lower oil pressure.
Truly profound advice :roll:
I wouldn't call it a "real problem" but you do have to be aware of the issue. Heck even a new cam or new valves pose a problem if you are sticking with those archaic non-adjustable lifters. Since I was replacing everthying none of that was an issue for me.
I never measured the lobes on the regrind I purchased but my assumption was they had been reduced. And even if I had measured them I have no specification to compare against. I did measure the journals and they were stock. FWIW both the journals and the lobes had been nitrided. Not sure how much that may have added dimensionally or how long it remains on the surface once you fire it up. I think it is sacraficial and dissipates rapidly.
PS> For a production shop churning out lots of regrinds for many different engines I would imagine build-up with a metal spray would be child's play.
