I'm a Gold Certified tech for a Holden dealer, been way used to it since '04.

They do get carbon build up on the intake valves and intake runners, which hurts performance over time and in really bad cases can damage intake valves and other components. A catch can lessens this to an extent, but my mechanic recommends spraying a decarbonising solution down the intake from time to time. Eventually with enough kms all of these engines will benefit from a tear down and a proper clean. This is recommended at the same time as they do timing belts, cam followers, etc. I doubt many Cobras will be doing that many miles though - in the order of 100,000+.
Been decarbonising VE SIDI engines since the problems starting arising.

If I owned one, I'd fit an air/oil separator ventilation tank including a replumbing job.
And possibly a electronic water/methanol injection system.
