Tore down to the heads. Removed #1 head that has bolt repairs needed and sent it to shop for repair. Combustion chambers look great. No defects evident in valve train or push rods. Engine very clean under valve covers.

Thinking about ignition system changes, intake replacement and emission system reductions.

The reason I sent the head to the shop for repairs was that on my attempt to easy out the broken bolt, I broke an easy out and the remainder is in the drilled hole. The shop (NAPA) looked at it and the "machinist" said he didn't want to touch it with the easy out in there. Maybe he knows best, but......

I am glad in retrospect. I think I can take a teeny drill bit (technical talk ) and drill around the easy out. I am on the road for two weeks but will drill into this when I get back mid Oct.

Any other suggestions (other than springing for some 70's heads as my right brain has been screaming at me)?
