Engine teardown was a little underwhelming. I knew I would probably be making some changes, but it turned out I would be making more than planned.

While the heads have been redone with new valves, casting numbers showed that they were the old 70s smog heads. Not really what I want on this project. Aluminum heads would be ordered, and something along the lines of 64cc chambers and 180cc runners for a good quench.

Pistons ended up being some standard P1534 flat tops (10:1) but I was seeing some rust and scores in the cylinder walls. Moisture had probably entered in through an open valve over the years:
