IF, the marks were from pistons too tight, you should see, almost like ALUJIMUM like deposits in the marks. I'd just drive it & DON'T WURRY! BUT, WHUT DO I KNOW--------------?????????????????????--(The Dorg's SMILIN')

Right, Bill. I am definitely influenced by the attitude my father passed on to me, similar to your philospohy: "It's a Model A Ford. If it runs, drive it." But I'm a little fussier. And it's more expensive to fix problems now than it was in 1955. So... I fuss.

No aluminum deposits observable.

That seems like a lot of carbon for only 1500 miles.

Why fuss with it. My opinion, (for whatever it's worth??) IS, if you put an engine together properly, use good parts, have CONFIDENCE in your work, just drive & enjoy it! I've seen folks fuss too much & literally destroy a car by taking it apart, puttin' it together, etc & literally wear out the fasteners & usually end up with a sub-standard performing car.
MAYBE I'll just learn to keep my opinions to MYSELF & get some of my own things done! Sorry if I sound TESTY, you should see me when I get REALLY pissed off & run out of "HUMOR"??
I only post helps that have worked for me, personally, in all my years of auto repair----------BED TIME!

I agree! I was hoping someone like Kurt would address that as I certainly don't have the experience to even speculate with any reliability.

I agree, and I'm still wondering why no crosshatching is showing. I would remove the pistons and remove the rings from the pistons, then check the clearances. I'd then give the cylinders a light hone and put it together again with correct clearance on the rings and pistons.

When I worked at the auto shop I hot tanked an Olds engine for a customer. He brought the pistons and heads in to show me how he had poished them to look like a mirror. He figured it would not have carbon stick to it this way. He didn't properly clean the cylinders after honing them, and wore out a new set of rings in one week. So he tore it back apart and showed me the pistons and rings. The pistons had just as much carbon as any other non polished engine. The rings were sent in for an analysis, and it was determined he left grit in the cylinders after honing.

can you rock the pistons any in the bore---left to right

The pistons do not rock in any direction.
