I'm in need of a little insight, from those of you with experience as I have very little exposure to gas engines in our hobby beyond a converted G26.

I have a new 3W80xi, upon unpacking and inspecting it I noticed in the casting of the head, near the base of two cooling fins there are a couple of casting imperfections which have left small holes, a few millimeters wide, in two different spots.

In the fin itself I would think nothing of it, but since this is at the base of the fin, along the outer cylinder wall, I just thought I would ask all of you with experience if I have anything to worry about.
