Bottom line, you shouldn't really just start stacking spacers to get to a fit.

Its 43mm of spacers under the stem in that pic. At the top end of things for sure.
It's a steel frame thread and many use steel forks. Stack away on a steel steerer. It's partly why people have 80mm of spacers on a surly last- because the frame stack height isnt high enough and a steel steerer can handle that much without concern.
