But very few engines now have standard factory cams . Most have either
been re ground to another specification or the cam replaced and the clearance of these could be different from original standard cam .
Do you know the valve timing of the engine .
Inlet opening & closing , Exhaust opening and closing to try to identify which cam is fitted.

Thanks Geoff
I only found a notice of a PO that a 403 camshaft had been fitted. As you mentioned there are two options - early and late. I guess less clearance will
end in troubles.
I don't know the valve timing and I don't know how to generate that data. In the files there is a drawing. I will look for it.
