That seems to be the problem- - - -the cam grinders I've been in touch with so far don't have the correct master cam. Since the acceleration ramps are a different height and duration on a hydraulic lifter cam, the one I've got that's in good enough condition to regrind can't be used "as is". I'll try the links that have been provided to see if anyone is set up to grind my cam. If not, I guess I'll have to buy a new one, or someone else's regrind.
