i wont do it to my NBS, i had issues on 3 other cars i did do it on, only one did it work right.
i wouldnt worry about it, most of your carbon is from the PCV putting oil in the intake
Yeah don't bother. You're not driving a 72 with a carb.
Just clean up Mani as good as you can (don't touch runners IMO (unless you can do the clean up like surgery) and get yourself a catch-can and hook up to pcv system to minimize blow by in the future.
More details in this? Is there a write up?

I'm assuming you're talking about the catch can?
Not sure about a write up but there's gotta be somewhere, it's incredibly common on LS. I'll never run any of my motors without one.
Basically you just get a quality catch can (there are some shitty ones out there that won't trap all blow by very well), then you just plumb it in off of the pcv valve nipple on the driver's side valve cover and back into manifold. Mount the catch can somewhere sturdy and easy to access to dump it.
