That would be a "hardweld" cam.
It uses a "spray" welding technique. The regrinds are just like vicious mentioned, cutting down on the base circle. Therfore you need to shim your lifter, or in our case a HLA so the radio maintains similar to stock.
Case in point, my cams.
Going from .375" to .412" lift. I am being told to use a #10 washer (.030"). I'll be dialing out the factory overlap with aftermarket Cam gears.
