I am running one right now in a sbc 383. Everything checked out good when we degreed it. I haven't run it long enough to say if there will be any metalurgy problems or anything like that. The only thing I noticed was that the edge of the front journal did not have a chamfer on it to allow the timing gear to be installed easier. That did not cause me any problem I added the chamfer myself, it probably just bothered me more than most because I run a machine shop.
