There isn't much left to examine.
There are only a few things that will affect the firing of the ignition. You have already looked at most. The distributor cam gear is left to examine.
With all camshaft manufacturers there is always the possibility that the camshaft itself was not indexed properly before it was ground. I have had issues with aftermarket camshafts.
In my case it was Compcams and that simply had to do with insufficient "quality control" in setting up the camshaft blank before it was ground and the company only spot checking one out of three finished camshafts before shipping them.
With a custom grind, theoretically the procedure is different and it is all set up and indexed by a technician. We just don't know the procedure Bullet cams would use to actually grind the lobs though.
It might be better to set it into a program and let the computer run the machine through a CNC procedure or that might have pitfalls as well.
To find an error in the ground profile at this point though would mean "indexing the cam", which is an SOB if you ask me, but I begrudgingly agree that it is necessary to verify the cam is "right on".
