OK, that explains why I couldn't fit even a 0.01 feeler gauge in between the rocker and valve stem. I was trying to detect movement of the rockers by using a feeler gauge, but that wasn't working so I just eyeballed the rockers on the #1 cylinder. I made marks every 5 degrees on the flywheel and used the timing pointer to read the marks as I saw the valve open or close. This is not exact, but after spinning the engine over a few dozen times I got these numbers off the stock cam:

intake open: 15 degrees
intake close: 75 degrees
exhaust open: 265 degrees
exhaust close: 350 degrees

180 degrees is one turn of the balancer/flywheel, two turns for a full 360. Now I need to figure out how to convert these to ATDC, BBDC, BTDC, and ABDC.

The inliner cam chart list the specs for the integrated head cam as:
duration @ 0.050": 172 / 188 degrees
lift: 0.389" / 0.406"
lobe sep: 102 degrees
