Nope, cams are coming off to work on the 5 liter (M119) engine, it's a bucket sort of arrangement. The M103 inline 6 has like a cam-follower arm that rubs against the cam and act like a rocker arm to push down the valve. Technically I don't thing "rocker arm" is the correct term, I think it's called a cam follower, but certainly it's commonly referred to as a rocker arm and I certainly knew what he meant. I't s anice set-up, each cylinder has a pair of rocker arms and each set can be removed with only 4 bolts.
On the M119, the valves are pushed down directly by the cam, I believe there are hydraulic compensators under the bucket, which is what the cam pushes down on.
It is funny that I have no problem with calling the M103 "cam followers" "rocker arms", but "lifter" makes no sense, I call them the "hydraulic compensators". Rockers rock, but in this case the lifters don't "lift", they "push". Hmmmmmm
