Lots of carbon is a sign of a rich fuel mixture or engine running too cool? Take a quess.

Forged pistons, standard tension oil rings, and running rpm's while cold will recirculate carbon throughout the system. No way to avoid it short of going with a cam with very little overlap plus plugging the egr and pvc. Anything with a bunch of miles will look pretty nasty inside.
