 617 rotax or 583
I presume you are referring to the cylinders and not just the heads,
which are on top of the cylinders. You should go to one of the online
microfiche sites and check if the part numbers are the same for the
cases and crankshaft on those two engines. Go to a web forum, like
Dootalk.com, and there you should get the info you need. If the case
will take the bigger cylinders and if the stroke is the same on the two
engines, then it might work.
