Best way to clean intake manifold?

Progress - lol.

Fuel injectors off to Witch Hunter in WA for a good cleaning, rebuilding and flow testing. Everything else starts this weekend when I have time and the rest of my parts show up. Hopefully be back on the road by end of next weekend.

 

Update: Seam Foam rocks!! I took everything apart, but since I ran Sea Foam through the system a month or so back, I couldn't find a lick of carbon build-up anywhere in the throttle body, butterfly valve, intake runners, T-VIS air intake control valves, or anywhere else I could see. God, I love that Sea Foam stuff!!
