Yes, the noses are interchangeable, but changing them will offset the starter for the larger (or the smaller)_ ring gear. You're best bet is to drill and tap the block for the straight pattern. Just bolt the starter with the one bolt that will work (outside) and make sure it's straight, then center punch (or take a 3/8 drill and just make a mark in the block using the starter bolthole as a guide) then drill and tap, cast iron drills and taps like a dream, you can do it with the engine in the car, just take your time.
