As some of you know the only off the shelf cams for this engine come from GM.
Another 4200 user and myself are going to get some custom cam blank cnc cut and if anyone wanted to get in on the buy the time is soon to speak up with cash in hand. The blanks are $400 per pair. Then the grind is another $700 to $900 for the pair so not cheap. Of course if there was enough volume then the cost will come down but, right not as far as aftermarket parts go, these are orphan engines.
