if you take the rocker cover off and have a look at thr rocker assembly you will see that the roller rockers have wheel that meet the camshaft, non roller rockers dont have the wheels.. i will take some pics of the two engines i have to show you the difference!.

dumb to this... so... whats a roller rocker ?

roller rockers are in the cylinder head.. basically cam followers!.. they pivot on a shaft hence the name rockers.. on one end the camshaft pushes and the other end taps the valves.. hence adjusting the tappets!...
the difference between roller and non roller is that the roller rockers have a roller bearing on the camshaft end to reduce friction!.. thefore being more economical and giving a little more power!.

im pretty sure infact almost 100% certain that all silver tops are roller rockers, black top is non roller.

but there are journal size differences between early and late silvertops ie 90 and 98bhp models.
