When I make a preliminary adjustment on the engine stand I use .007 intake and .011 exhaust.

After the engine is in the car I redo the adjustment with the the engine fully warm and running. Although it is not my favorite entertainment, it really is not that hard after one removes the inner fender panel and the heat shield on the fuel pump. At idle speeds there is hardly any oil splash to speak of. These later engines only require two wrenches to adjust which is much easier.

The hot and running adjustment takes care of many variables (ex: hot spots, growth in dia of the valve head etc.) all at one time and gives a long lasting result.
