The ignition cam can be installed on the camshaft in two positions, but only one is the correct way. ....If you haven't separated the two parts, nothing will have changed.
The "triangle" on your camshaft gear should point at the mark on the ignition cam (which appears to be a "dimple" or punch mark in your photos).
With the two cams mounted on the rod, can you rotate the ignition cam to see if the weights move freely, and the cam returns to its relaxed position?
As a general rule of thumb when fitting new piston rings, the end gap should be 003" per inch of cylinder bore. ...Example: for a 3" bore, the ring end gap should be close to .009". ......If the ring gaps on your existing rings are .015" or less, I would not bother changing them.
I don't see any sign of a compression release on your camshaft.
....On engines that have compression release, exhaust valve clearance can be set wrong if the tappet is raised by the ACR. .....To avoid that, I would always adjust exhaust valve clearance when the intake valve is fully raised, and set intake valve clearance when the exhaust valve is fully raised. ....This insures that the tappet for the valve being clearanced is riding on the base circle of the cam.
