Valve Cleaning?

Has anyone done this on their N54 yet? DIY or a shop, i'm just trying to get some information. Anyone know if a shop would do this and scrub the valves by hand?

I'm willing to attempt this with someone if you've been thinking about it too...

Blasting

Some guys have been doing it in the Dallas area recently. I will get mine done there next year. They had some posts on the e90 forum.

It's a little messy but I've seen people fill the intake ports with b12 carb cleaner (some nasty stuff) but it will eat the carbon pretty good. To be honest the walnut shell cleaning is such a mess/ headache compared to just letting each intake port swim in some carb clean. Remove intake mani, roll over each cyl to close intake valves and let em soak
