YZ400-426-450f parts interchange

I just acquired a 99' YZ400f.I was wondering if the 426 or 450 cylinder would fit on the 400.And what other parts are interchangeable.The bike I have had the piston hit a valve.I haven't got it apart yet to see exactly what is wrong with it.But any help would be great.
