Should I Cut this off?

Here are some sweet 062 Vortecs I am about ready to top off this small block. After taking a close look at the chambers it seems there are some areas that could use some attention.

The main offenders seem to be the point of the heart shaped chamber. If I smooth these out will it pick up any CFM?

It also seems that the area around where the valve seat was cut could use some attention. Should I worry about these areas?

Thoughts?

Thanks for the input.

DoubleVision:
I see the area is around the edges of the valve, and if a 5 angle valve job promotes more CFM than a 3 angle valve job, then this boundary layer my be important. I do tend to over think things.

Yes I forgot to mention one of my concerns was sharp edges retaining heat and causing pre-ignition. The engine will be about 9.9:1 running on pump gas with flat tops and iron heads.
