Well, look what we have here!
Why couldn't you get a 2.1" valve in without moving guides? A quick measurement and simple math tells us valve guide spacing is 1.875" =/- .002" a nice nominal number. So half of the valve diameters added together better be less than 1.875". I get 1.85" with a 2.1/1.6" which should leave .025" between valves--your valve guides better be good and valve train stable. W2/W5 OEM heads all have the same spacing. Also most off the shelf pistons barely have room radially for a 2.08" . J.Rob
p.s. See YR, it's not so hard to add actual information. I even added a picture for you.
