I pulled the head of the SD. Pics show findings -

First pic is cylinder 1 cross hatch. Looks good but there's a band below the ridge with little to no hatch. Is this the result of a bent rod?

Second pic is cylinder 2 cross hatch. The hatch is clear to the ridge.

Third pic is the crown of cylinder 1 at TDC. More carbon than the others. What's the white ash? WVO?

Fourth pic is the crown of cylinder 6 at TDC.

Fifth pic is the valves of cylinders 1 (right) and 2. The other cylinders look like cylinder 2. What's with the crud on the exhaust valve of cylinder 1?

More to follow...
