Forged crank machining

Looks like I may need to go down to .030 on the rod journals, on my factory forged 440 crank to get the stroke equalized. Going on the low side of .010 on the mains for the little bit of extra oil cushion. I was hoping to only have to go .020 on the rods, but we'll see. Any problem in going that far down, does anyone know? The machinist said they do it all the time, and it's a very reputable shop. This motor won't see over 7000-7200rpm and a max of 12lbs of boost.

Thoughts?
