Well the head is so easy to take off, are you going to do the top end? Sometimes when you renew the top, it blows the piston rings out. Might be best to do the rods, mains, and re-ring it. Good luck, let me know if ya need anything, ok? Need a hoist. We did all ours in car. Used a hone to deglaze the cylinders.
I have resealed a few of these. If your piston comes up, valve guides being bad should not cause the valves seating to be affected. With the piston up on the compression stroke there are 2 places you can lose compression up, down. The valves or valve may not be seating or ring problem. A wet cylinder compression test will tell you which. Squirt some oil in. The oil you squirt in seals the rings to bring compression up. Bad rings. It has little or no affect on valves. Try a wet compression test so you'll know where your going. I am no total expert, no such thing. I hope I helped you. Good luck. Let me know.
