the fl250 stock head on the engine has two spark plug holes in it. they have a dg after market head for them as well and water cooled one. the 250 has 4 head bolts and the head has cooling fins, but a 350 and 400 have 8 head bolts. and is  domed with no cooling fins.  Are you sure its not a snow mobile motor. hope this helps. more info or a pic would help us id it.
