It's hard to see the piston thru the plug hole, plug is not over the top of the piston.
If you have air moving then your rod and piston is intact.
Go get a head gasket and remove the head and check for proper movement of the valves
Sand the head flat and put it back together.
Then put some gas in it and fire it up.
