Crank Question: Do I need to regrind?

Another rookie question...this time about a small scratch that developed after initial preassembly.

Here's the story.

I checked all main and rod clearances using micrometers and a bore gauge. Everything checked out.

I then installed the cam, crank and timing chain kit (using Napa engine assembly lube just like final assembly.)

I then test fitted my heads, and went to work on getting my valve train geometry right. (Thanks again for the help of this forum!)

I got everything where I felt comfortable with the set up...then I disassembled the whole thing.

The only trouble is that when I pulled off the rod caps on the #1/2 journal there was a new scratch about 1.5" long, right down the middle, between the rod bearings. (See attached picture for detail)

Question: Do I need to have my crank reground/polished? Or is this a non-issue?

Thanks again for any help.
