The only thing I've seen that causes dark intake ports is reversion, which is exhaust gasses getting into the intake at low rpm due to excessive cam overlap.
Some of the exhaust valves were not fully seating due to the out of round seats (had to sink the valves .040 to clean up the seats). So, that wouldn't surprise me.
