I have never seen a torque spec for the rocker arm hold down bolts. I just tighten them, but you could go with std torque chart if you want to torque them. The important thing is that when you tighten them down you have not tension on any valve, back off the adjusters. Tension will cause stress on rocker arm shaft and pushrods. Not a big problem on an M but on the six bangers like the 400 series it can get you into a big hurt. Also on the M, make sure the rockers have a little bit of side play after tightening them down, may have to loosen and tap support over a little. Can cause valve hang up, push rods come out of place etc. Often over looked also.
