Hi Y'all, having finished the carburetor rebuild I'm onto the engine refresh now. I am doing an upper end rebuild because basically every seal is hemorrhaging oil up top including the upper head gasket. Oil just runs down the front of the engine and I'm sure its leaking from down on the lower end too. I am gathering components I will need, seeing as the upper head is coming off I'm thinking the lower head has to come off as the lower head gasket will be decompressed with the removal of the head bolts. I found piston rings for fairly cheap that I will order just in case, the compression is a hair low in one cylinder but I'm fairly certain it's just the old seals and crusty valves no longer sealing properly. I'll definitely do the obvious and clean/lap the valves, remove carbon buildup, replace the valve shims, hardware, etc. It's going to be a blast but any advice would be greatly appreciated, do y'all have any advice on how to extract the engine from the frame and disconnect the drive shaft? It will make everything exponentially easier if the engine just isn't crammed in the frame for this. This will be the most in depth engine work I've done so far, that being said I've done this on a car before so I'm thinking it will be similar.
