Does anyone know if genuine M.B. valve guides come with finished I.D. bore
or do they also need to be reamed after installation for use with standard size O.D. valves? These are for the '91 4.2 gas engine.

Completely different area but do most owners exchange their Becker door speakers for newly refurbished Becker units or do they purchase other aftermarket brands when the originals die?

Thanks,
