I don't have to get the headgasket in exactly the right size?? Does the permatorque come in anything other than 86.5/87?

I need new rings too so the exact bore is pretty important for that. I ordered .030 over rings, but the engine builder was pretty sure it was 86.5mm bore, he said it was the original Magnus-designed Ross stroker pistons from 4 or so years back. Maybe I should call Magnus and see if they still have the order specs on file. Or if I could find the sheet that came with the pistons...
