Might I suggest you get a bore-scope, remove the spark plugs and have a look inside each cylinder for any damage to the pistons cylinder walls. or debris before going any further.
Should I redo the compression test, both dry and wet with the throttle open and write my results down and compare?
Yes, but confirm as to the above.
If I try to start my motor up, will I damage anything if the valves are bent …
Possibly … damage / drop valve seat(s) (if that hasn’t already happened) snap a valve, damage a piston,head or cylinder(s)
would I have time to turn the motor off if I heard anything out of the norm? So I could see what my results are at operating temp
Most likely not. If you hear something wrong, the damage is likely already occurred.
Can I compression test And get a accurate reading on a cold engine? It’s been sitting cold for a few weeks now.
There is a procedure on how to do a compression test correctly.
But in your case you can get ball park numbers to see if the engine has enough compression to actually start.
