I pulled the head tonight and have a valve with a small chunk missing out the side of it. So a valve job is next on the list. I also noticed that all of the exhaust ports were dripping wet with oil. I would have expected that after letting it idle for 30 minutes before draining the oil that the exhaust ports would have been drier.

The bores in all cylinders look good and even, no unusual shiny spots and no rough spots. None of the cylinders have a ridge at the top that can be detected with a finger nail. I measured the clearance between the top of the piston and the cylinder, and pushed the feeler gauge down until it hit the top ring. All 4 cylinders have a piston to cylinder between .011" and .012". My model a repair manuals don't say much about this particular dimension. Any thoughts on if this is an issue..?
