Guys motor does turn freely and valve train from what i can tell is in good working order. I would think based on the wealth of all your knowledge that its either stuck rings or head gasket. I assumed by adding that ultra lube that's about as thick as honey it would bump compression a bit and it did for #6 from 30psi to 32psi but still 0 psi on all the other cylinders. This motor I had cranked over about 50 times trying to start it so I would hope these rings would be unstuck by now. Who knows? Probably right on needing a rebuild.
