andypurce Posted July 6, 2013 Share Posted July 6, 2013 Does anyone know where to get a set of oversize (service) valve guides for the L series 6 cyl heads? I have 3 heads (2 x N42 and an E30) the E30 guide hole has been reamed out by prior owner to suit service guides. These are 0.2mm oversize (being 12.223mm-12.234mm diameter) and both intake and exhaust are 59mm long. Also be interested in anyone who has fitted 42mm Intake valves to an E30 head. I am interested as this is a high compression head due to the small chamber volume and mated to the larger valves could be good (when ported) for a good race camshaft.
