That makes sense since they are 4032 and can be ran tighter... but that does seem pretty tight. IIRC Mahle 4032s recommend .002-.003 for PTW

I'm not ignorant to how small .000x is...

Maybe I am being hyper critical.
Thats why theres tolerances. Its impossible to get exact spec across the board when your talking about ten thousands of a inch. Even if you could its not like everything would stay the exact same at different temps.

It is very possible to do that as long as everything checks out and theres nothing wrong with doing it like that.
