My main concern here is that once I remove the tensioner (Waiting for a regular L shape allen, cannot fit a socket and ratchet, smog pump on the way, might have to remove it, the pump.
And I am hoping that once I remove the tensioner I'd be able to remove the sprocket. Do you have any advice on how to attach the chain to some place so it does not fall? Thanks very much for your time and help. Ed

Secure the chain by maintaining upward tension on it with tie wraps or mechanics wire. It doesn't need to be pulled/secured from the absolute top. Tie wraps could go on the chain sides at the level of the top of the head around a long screwdriver across the cavity opening. If the links around the cam sprocket aren't pulled tight that is ok. The goal is to not let the chain get lowered off of the lower sprockets that you cannot see or reach. You'd be amazed how a slight drop in the chain can cause it to fold on itself, slide into a hole and get bound up.
Good luck!!!

As SB said. But going on memory I THINK there is a tab on the cover of the engine below the crank sprocket that will prevent the chain from getting "off time" at the sprocket.
No matter, make sure engine is at TDC on the #1 compression stroke.

Hello!
I just wanted to thank everyone here for all your time and help. I ended up attaching the sprocket with 2 of the bolts that had a bit of thread left, went to 8mm from the original 7mm, tapped them, then pull the sprocket, put a piece of scrap metal between it and the cam and bored the threads out of the holes to fit perfectly the 8mm bolts. I also added a fourth bolt and used red loctite. I also had to replace the cover, as the bolts scraped and cracked the original one. Thank you again!! Ed

The threads on the bolts are damaged, but are the threads in the camshaft bad? It may be a long shot but carefully examine the camshaft threads. You might get lucky and be able to clean them out with the correct tap, avoiding the insert work.

I'd be worried that the inner hole is wallowed out.
