Yeah, I definitely second the Sharpie marking thing Chris talks about.
All of mine have been marked like this since he taught me that trick. It sure does make pre-flight of the head easy from the ground! All of my head bolts (Kingpins) use castle nuts, and the cotter key fits inside a longitudinal channel on the bottom of the torque tube. No nylocks. I recall Dan something up north built his own heads, used drilled kingpins and castle nuts but didn't install nay cotter keys. That bit him bad. Don't leave out the cotter key.
