Most gasket kits that I have investigated come with .038 or .050/.055. You may have to ether poke around some or order the head gasket separately.
Fee's for head milling vary a lot depending on the shop, location, & amount removed. I have paid as little as $35 for the pair of head just to give a resurfacing type of cut to $100 for removing (IIRC) .050. This was also some time ago. I forgot what the was charged last.
