Yes the cams were changed, the earlier/shorter vane ones require the use of the long cut out plug. The poppets are essentially the same but there is a break in the 2 profiles a and c unlike the earlier poppet valves. no change in lifters apart from colour that i know of. bodies were changed yes hard to explain earlier vs later without a picture.
Do not use any non genuine parts in the carbys especially primer caps, needles, diaphragms, and even cut out plugs. They do not always work correctly or last like genuine parts. Poor man pays twice.
