All went well. Now I know what my problem is: 1 bad/noisy lifter. Going from 1/4 turn to 1 turn made the noise louder and defined it. Now I can rest easy knowing exactly what's wrong. I'll back out 1/2 turn and see. Maybe go back to 1/4. Anyway, it will have to stay as is. I'm about to move. It'll be months before I get to it. I'll try SeaFoam, etc to improve the situation. I guess the engine sat way too long after being build and dyno'd.
