longshot piston id help (terrible pics!)

[gridgway]

I have been trying out my new endoscope. I haven't got it hooked up to a camera yet, but took pics from the screen.

I was looking down #4 sparkplug hole on my "2.7RS recreation" motor which was built from a 76 CIS motor (no history), now running MFI.

The pics are here:

The pics don't show much (I was hoping to see pockets), but do seem to have the same "mahle marks" ( the oval and the "M") that are shown in the first pics here:

Help ID P's & C's - new tear down

Does this help id the pistons at all?

The motor is getting a refresh starting next week, so all will be revealed, but I was just intrigued to see what I could find.
