Race valves

[1968jimclark]

Could any of the engine-builders suggest a source of race valves as it has been suggested they are on 3 month delivery(from where I am not sure)?

G&S valves.Yes they are on back order.The one piece valves are only really needed for the 24hr race the standard valves will do the job ok until then.
