So I bought a compression tester and tried if. Results were 0 the needle didn't move during test. I checked the key under the flywheel bolt looks to be in good shape. Not sure what's next here. Attached is photo of key

This isn't a bulletproof test, but put the spark plug in, and take off the oil filler cap, rotate the engine over and listen for air "hissssing" a little bit is normal for an old engine, but if it seems excess it may be the rings...
I would try replacing the head gasket as bert suggested, or at least look for blown spots.

May as well pull the head off and see what’s going on. With 0 compression it will have to come off anyway.

Thank you all!

Problem found the ring under the intake valve popped out of place. I was able to seat it back in and and have gotten alot of compression back. I have a exhaust gasket and head gasket on order.

Attached is vid of issue

Once I have the gaskets I'll let you guys know what happens!

Thank you all so much!!

Glad you have figured out your problem.

That is the valve seat and it will continue to do this
IT popped out because the head got too hot
Some people have managed to get by staking the seat in position with the valve in place.

I just replace the head after working out why the head is overheating in the first place

Sounds like a stuck valve,
or something like that....
