Default poor casting...or damaged?

I've got a set of 799 heads all ready to go, but I'm cautious about the casting quality in a few places. Check out the porosity between the valve seats. This one is the worst, but a few others have signs as well. It appears only to be on the surface. Is this a poor casting or detonation. Usable for a NA motor??
