then, one of them more than the others.
soot is exhaust gaz exiting by the non closed intake valves during compression strokes maybe.
seats have been machined i guess.
the guy did valves adjustment ?
is it difficult to start the engine ?
why to torque the heads bolts ?
it's supposed to be done if you ran the engine.
the mls gasket do not need re torquing as i know.
are you sure your intake gasket is not leaky and let your head to suck soot ?

Actually, this is a possibility: the intake gasket at that port could have been leaky because I didn't use a torque wrench on the bolts (I realize now I should have, and I will next time), but wouldn't I see soot on the gasket? I'll check it. Also, I'm not sure what you meant by torquing the head bolts: do you agree with doing this or not? I'm going to do that per the manual (90 degrees) either before or after my next thermal cycle. I plan to check the valve clearances too.
