mahle 1mm o/s cosworth piston bore size

Could anyone confirm the bore size when using 1mm o/s mahle pistons (91.77mm). I'm sure the machine shop will know for sure when I drop them off. This is just for piece of mind.

I would imagine it will be 91.825mm.

Question for the engine builders I guess.

Thanks guys.

I'd supply them with at least one piston to measure, if not all four. Usually Mahle are pretty good on size, but its worth checking them before its bored.
