It has been skimmed by 0.030” how would I calculate the new volume and should I worry about it?

You have taken around 2.00cc out of the head, which will raise the compression by around 1 point ie 9.4 to 10.4 but this doesn't take into account any valve recession which can affect the rise quite substantially.if you want an exact you will need to measure it.
