We have discussed this and he will check the cover when he gets a chance. ..................lm

If the former, should be an easy fix.

I think that was the trick, Ed.

I didn't find any evidence of the cam being off centered and in need of a good hammer, but the new screws I put in just weren't quite long enough because there's no threading the first 1/4" into the holes in the head, so they weren't tight against anything. I put in longer bolts and cleaned up the surfaces for those new gaskets. I did notice that one of the gaskets has a "cutout" that the other one does not. It's on the bottom of the gasket and only on one side, since there's oil passages on both I wasn't sure where that gasket should go, but I put it on so it wasn't facing the exhaust (in case it wanted to leak again).

I took it around the block and it's leak free on both sides.

It does shift though, it was just a hard shift and after adjusting the clutch correctly I can move it through all of the gears alright. Front brake barely grabs anything, but I'll worry about that another time.

Good deal.
I'll cross my fingers and hope the leak is gone. ......................lm

I agree. The leak is above the head gasket said unlikely to be from there. Either the cam cover or the dreaded separation of the combustion chamber "skull" from the head casting.
