408 Stroker Build / Intake Question

I run a Scat cast crank in my engine and had the shop turn it 10/10 to get rid of run out and other imperfections. The shop said I could have used it out of the box but it would not have been as durable or run as smooth as a perfect crank. Imperfect cranks put a lot of stress on the rotating assembly which is something you do not want. All cranks should be looked over by a competent shop prior to installation.
