Pistons arent forged iirc, thus the expansion rate when doing high speed, long term wot jaunts. SVT didnt see them as an issue in early engine development, as opposed to the rods used snapping like toothpicks, which is why they went with Manley's. Pistons arent necessarily the weak spot unless you heat them to the point of causing engine failure.
your Reman motor should utilize 99.9% of the same assembly parts and installation procedures as they did from your original, just now your valve cover name plate means jack shit.

I thought everyone knew that we have forged pistons
They only build a specific number of replacement engines on the Niche Line and when they're gone, that's it (those ran out years ago...)
Only the hand-assembled, Niche Line engines get a tag

Same thing happened to me when i blew my first motor.. Ford replaced it under warranty with a reman... You could've removed the tag and reinstalled it on the reman, of course this would be completely be for cosmetic purposes.. As your reman was a mass produced engine...
This was one of the excuses i told the wife, why i didn't want my first cobra anymore.. It worked, i sold my first cobra and bought a vette..

The pistons are forged from Zollner.
I don't live in Hell, but I can see it on clear days.
