Rocker Box Help

I am about to replace the gaskets for the rocker boxes on my '14 Ultra. Do any of you have a spec sheet/instructions with the torque values?

Just for clarification; rocker boxes or rocker box covers?

Service manual says 15-18 ft.lb. but I never use a torque wrench on those fasteners. I snug them down pretty tight and then add another 1/2 to full turn. Rarely have a leak but if there is a leak, I go back and add another 1/2 turn on each fastener. When done, I might have hit the service manual recommended torque, don't know but I have found that it is best to stay on the low end of the specified torque range to avoid stripping threads.

What about the metal gasket? Torque value and pattern? I could have been clearer in what I was asking.

I am doing the bottom and top gaskets, front and back. Is there somewhere I can download the instructions and torque values?

Most popular head gasket is the Cometic MLS gasket; it comes instructions and torque values. Rocker box gaskets torque to 120-180in.lb. if IIRC. I don't know anyplace other than the service manual (you shoud have one) to find all the HD torque values. Some have changed from model year to model year.
