CSL exhaust valves and gas flowed head

Out of interest why does a std m3 and Csl share the same inlet valves - 11347830889
But they don't share exhaust valves ?

Csl 11347833676

m3 11347830888

They both list the same sizes. Is it CSL tax ?

Inlet 35.0/5.95mm

exhaust 35,0/5.95mm

Any ideas ? Sodium filled ???

Cylinder heads list same part no. But mine is heavily gas flowed on the inlet side and throttle bodies matched the same. Looks to be CNC machined. Exhaust ports are un touched.

Can anyone else tell me if they know of any other gas flowed csl's ?
