That is normal for a engine that has some valve leaks or a large overlap cam.
What you see is the primary is washed by fuel all the time and the secondary is closed most of the time and you will get this black soot

The clean butterflys are the secondaries. The primary's have gunk build up from poor quality fuel. Run Chevron, Texaco or Shell gas with Techron and they'll stay clean.
