Deck it and run a 1.5mm head gasket.
Earlier i was saying (this is my personal opinion, others may dispute), "if the machine shop cuts only a little bit off (.001"-.003" [off of the head AND block combined] when they deck, you can use a 1.1mm headgasket"
BUT... If you are ordering parts before you get the machining done, just get the 1.5mm head gasket. I say this because if they cut a lot off you're safe from too high of a CR, if they only cut a little off you're safer from knock.
On another note, you should get the machine shop to gap your rings for you before the hone so it doesnt get marred. Youll probably need to rent some sort of torque plate as well unless your machine shop does a lot of SR20s
