Which head
#2
If your engine is three bearing then I think it would have originally come with a high compression head - these do work well.

However, if a previous owner suffered plug oiling or main bearing thump, they 'may' have fitted the low compression head to suppress the effects of these problems.

P.s. the 'brass' pin you mention is normally steel, in my experience, and locates in the centre camshaft bush to stop it rotating/moving.
