Did you actually read what I posted? I didn’t excuse the shop for not using the plate. I explained that the OP isnt a machinist and he has no business tell the shop how to fit a piston. And he doesn’t. If he knew what was what, he’d have known pistons today aren’t like what we had years ago. You can finish a bore to nominal size and it will be right unless the pistons are poorly made. Then you send the pistons back.
I’d be pissed they didn’t use the plate. But there is no unscrewing that now, because putting the plate on and honing it again will certainly make the bores too big. That’s why I said just run it unless he wants to send the pistons out to be coated to make up the clearance. Or start with a new block.
You have to be pragmatic about the situation. It is what it is.
