Anyone know 74.5mm Wossner piston specs?

I need to find out what the tollerance specs are for the bores after a rehone for 74.5mm pistons, i.e how big can the bores be to a thousandth before they go out of spec?

0.03mm i think

I just spoke to wossner in america and he reckon i can take off 0.001" without any problems which works out as 0.0254mm doesnt sound like much but its all i need to clean the bores up, gonna give them a quick hone to remove some of the very light scoring which you can see but cant feel, no doubt caused by the pistons melting!!
