455 Olds Crank question

Hello Everyone,
Just got a call back from the machine shop on my crank, it is a Nodular crank for my 455 build and I am being told it needs to be turned to 20/20. Anyone know of or had an issue with a gring at .020 or should I look for a different crank?

You’re fine at .020/.020 and with a Nodular crank if you keep your hp level below 600.

Cool, thanks for the input. The machinest had to bore the block to .060 over so I guess thats the last bore on this block. Would you suggest any 1 bearing brand over the other Cutlassefi?

Federal Mogul main bearings 108M in a .020 under. Rods I just use the Clevite P bearings. And the Durabond 06-B is the best cam bearing to use imo.
