johnta/Quick-silver: I wondered if the lifters might be solid based on the way they were acting. I pulled one. Looks hydraulic to me (I can see the plunger/keeper inside). See pictures. I see what you are saying about the lifters pumping up. I have adjusted valves years ago on a running stock engine by sound as well. I guess I could do that here. Why do all demonstrations show adjusting the valves on an engine that's not even in the car? Those lifters haven't had a chance to pump up.
steve25: There never was a coolant leak. I think I made a false assumption on the head gasket being bad based on the two cylinders that had no compression being adjacent. If I had done a more through diagnosis, I wouldn't pulled the head in the first place.
