Would you use a forged crank that has been turned 10/10 in a 6-71 small block application?

Yes. .010 is not enough material to even sweat over. To help ease your mind; take a quick glance at a .005 feeler gauge. That's the equivalent of material that's removed from the 'perrimeter' of your crank shaft... Don't give it a second thought.
Some guys posting on this forum may be old enough to remember back when Super Stock racers took BRAND NEW cranks and immediately turned them .030 and .040 to reduce the reciprocating mass on their race cars. It also allowed them to turn higher rpms. Then, guys like Herb McCandless et.al. took these cars to the track and blasted round after round of 9-10,000 rpms on these same engines - all season long.
For a street/strip application .010 or .020 is not a problem
