The K series isnt the onlee ones with timing chaina. F20-F22C have timing Chanes and so does k series.the F series in the F and K are designed to loose about an inch off the front of the engine.
You're right, the F20C has a timing chain that drives twin helical scissor gears for the cams. Very cool system, the scissor gears it uses are amazing. I think they take like 150 lb-in of torque to rotate...something ridiculous like that.
