I think the issues will be whether or not a rimflo valve would be better in a
fast road engine or whether you might want a sodium cooled valve on a racer.
Not least remember all that valve trouble Vauxhall had with Formula Shell
petrol a few years back.

<< Looked at a Vauxhall/Opel/GM Vectra head that had gone to pieces. The
exhaust valves are the same dimensions as the Midget with the exception of
the length of the stem (longer by about 50 thou) and the diameter (narrower
by lots). Since it appears to be a stainless steel valve with flat back and
narrow stem, is it going to be of any use to the 'fast boys'? Individual
valves come at about #19 each, slightly higher than steel normal valves.
How much for the stainless ones?
