What R value to blow in ceiling?

My pole barn is going to be used for hobby woodworking. I'll keep the temperature around 40-45 when not in there and 55-60 when working in there. When I need to spray waterborne finishes I'll get it up to 68-70. I plan on heating it with a propane ceiling mount heater.
 
My walls will be R-19 and the bottom of my trusses are 2x8's. My ceiling and walls will be 7/16" OSB. What R value should I do for the blow in ceiling?

Next summer I am doing shop remodel #3 and planning on insulating the ceiling as well. I am going to go all the way to R-60. The cost difference is not that much on the size of my shop, so figure why not. The more over head the better. Planning on using Owens Corning Atti-cat. If it turns out well, will be taking the house attic up to R-60 as well, with the same stuff.
