Installing OCC @ 50k miles, anything I should do to promote longevity?

[Slowdan]

Quite new to all of this, bought my G80 Sport yesterday as well as the JB4, OCC, Sparks, etc. It's at ~50k miles and runs like an absolute dream. I've done some research and I'm seeing that it's doing preventative maintenance long before, and I'm sure sure how quickly carbon build-up happens. Should I worry about getting it cleaned? What's the process and how expensive is it? I'm quite the mechanical noob, but looking forward to having this beast on the road, tuned, and safe.

I've read conflicting information about carbon buildup, where some mechanics are saying deposits can be problematic within 15-20K miles, and others suggesting that it would be wise to get the valves cleaned somewhere between 50k and 75k miles for optimal performance.

Some enthusiasts suggest that certain solvents can loosen and remove deposits, while others say that the "proper" way to do it is mechanical removal of the carbon crust with special tools, or walnut shell blasting.
