Got 1 head off. There are no dowel pins. And the carbon ridge on block seemed a little offset on the end cyl. Seemed to clean up with a little scrubbing. Light color on piston is reflection from light. How long can a motor run with no pins?

The corner head bolt holes the left side of the picture (outboard) should have collars in them, are the stuck in the cylinder head?

Ok, I found 1 on the floor. So I’m guessing the 2nd was lost by me. Kinda surprised by the amount of crud in combustion chamber.
