If I was to have my head machined how much would be typical to take off to gain 25-30psi? 0.02 sound right?

You can only mill the stock heads around .015" deep before going into the squish band area and you would need to have the head milled twice as deep or more with the squish band angle recut. I strongly recommend machining the squish band angle & domes anyway along with the head milling because the sand casting is not very accurate in the squish depth around the bore diameter once milled down.
