Mine had a lot of carbon on one cylinder and it happened to be the one with the burnt exhaust valve. I cleaned the top of the pistons with a roloc disc and use compressed air to blow out any debris. Usually, the clogged EGR port causes this buildup.

I use Seafoam once a month to keep the carbon from building up. If you need any help with the rebuild, please ask us first! Make sure the new head gasket is cut properly for the drainback hole.
