RR's Tappet Clearance?

Gentlemen,
Would I be wrong to interpret Rupert Ratio's "touchy feely" guide for adjusting the tappet clearance on my B44VS as 0.006" for the exhaust valve and 0.003" for the inlet valve?
Thanks,

B44 Alternator Repair

Re: Oil Filter base - warning!

In order to achieve a neater installation on my Victor I modified my "Norton type" filter base by drilling out the pipe spigots and tapping 10mm internal threads, I then fitted suitably sized banjo fittings. This gave more pipe routing options and worked well for me.
