54 VH Exhaust Valve Stem Diameter

My 1954 VH engine has an exhaust valve with a stem diameter of 0.375 (3/8") and an inlet valve with a smaller stem diameter.
I am suspecting that my exhaust valve is non-standard - can anyone confirm please?

Hi Ian,
According to the measurements on the Feked.com site your exhaust valve stem has the right diameter for a '54 VH. The inlet valve stem is a smaller diameter at 11/32" from their info. See following links :-

Thanks Keith, that has set my mind to rest, never thought to look at the Feked.com site. Also it confirms that my inlet valve is correct too.
Best regards, Ian

You could also refer to the table on the Draganfly site that lists all the Ariel and BSA valves with their dimensions.
