Good luck finding flow numbers on the Rotax Racing head. I've never seen them.
I do know that they CNC port the intake side but leave the exhaust side alone.
I've used the head before and loved it. Performance is better with the WCC big valve head though!

All I can say is when using the West Coast/Rude CNC ported Cylinder head. You better have tune up rite.!!
