I swapped heads a few months ago with some TEA LS1 heads. I'm keeping all my stock parts so I can take all the mods out in case I have a hard time selling the car modded. The stock heads I removed have a ton of carbon buildup on the valves and everything. I was really surprised to see all that buildup after only 38K miles!

What's the best way to clean these up and get all that buildup off of them?

There is a kit that they use at dealership. Hmm trying to remember!
