That's what we are thinking they are.
they are flat, with a slight "step down" that might only be a couple of pennies widths deep.
Only reason they were discovered was because of an unplanned head gasket job

You mean, unless the tune is spot on? or are you saying that even with a spot on tune, it won't do well?

There in lies part of the problem. We've not been able to positively identify the pistons. The only marking on them is a "ST" engraved in the center of them.
Thought they might be old SuperTech pistons, but after spending a good bit of time talking with a rep over there, we are certain that they are not SuperTechs.
Hoping to find some sort of model numbers or something on the underneath side to be able to identify them.
In the meantime, without knowing the exact brand of the piston, what would be the recommended process?
Is there any "use this ring..." or "do it this way..." to be better safe, then sorry?
my thoughts are, unless the pistons can be identified, to have a machine shop measure it out to know how thick/wide the rings need to be, then track down the right sized ring.
I just honestly don't know what makes a good ring, good. or if all of them are pretty much the same or what. low tension, versus standard tension. "normal" ring sets versus those "total seal" doo dads. and all that jazz.
