Valve guide seals

[Schurminater]

So on following the Plug colour thread it left me wanting to get an understanding of the fitting of Valve guide seals on Laverda triples heads, were they originally fitted, should they be fitted, are they a help or hindrance.
Be grateful to learn from the experts please.

Thanks in advance.

Fitted to all triples on the intake valves, state of the art at the time.
