My 75 Finally Gets The Attention It Deserves(This Could Take a While)
I got the heads off today and confirmed that the valves had all hit the pistons and that they're all bent as a result. But the damage to the pistons appears to be negligible, and in spite of sitting for thirty years (at least) with the intake manifold off, the rest of the engine looks pretty decent. I had been worried about the cylinder walls, but they look fine. At this point the crankshaft can be rotated by hand so nothing is seized up. Next comes tear down. Fingers crossed.
