Naw .090 would probably give you positive deck height. In regards to the deck height, have your block measured first. That way, you will know where the deck is before you have it milled. They are almost always too tall and crooked from the factory. What "I" would do is have it decked to the stock height. Tell the shop to square up the decks and make sure they are parallel to the crankshaft center line. Then, run the HP piston.
