just thinking here the head gasket has hole or is worn in the middle of the two cylinders when the piston is firing would that cause it to blow up into the other piston on its down stroke and be causing a problem like no compression

Good that you had 2nd thoughts and entered a second post to tell us about the blown head gasket.

Install a new head gasket and torque the head bolte to 18 to 20 foot pounds in the following sequence.
