I have been reading the feedback about different spark plugs with great interest. Does anyone have any experience of running different plugs in 'non standard' cylinder heads? My special is fitted with a Supaloy head. At the moment it has Champion L86C plugs. Would there be much benefit in fitting 'hotter' plugs such as the NGK B5HS or BP5HS?
