CP Piston Valve relief Modification

I am looking at my CP pistons and there is a very sharp edge where they cut the valve reliefs in. I was wondering if you guys typically smooth that out to a more round edge to prevent hot spots.

thanks

It seems to help if you use a light sand paper to take off the sharp edges. Dont go crazy or anything, just a little.
