Sounds like a neat project.
One most 175's you can not put the 200 cylinders on because:
The 200 cylinder liners are to big to go into the crankcase halfs, however a machine shop could machine the cases out to accept the 200 cylinders
A few 175's (late ones) were built using the larger cylinder hole!
No aluminum BS cylinders can be bored, since they are chromes lined
Hope this helps
