MG MGA - Valve Caps and Collets

Does anyone have any original caps and collets available from a later 1800 engine? I'm putting some 1.625" inlet valves into a Derrington Head and the collets and caps from the smaller valves I have won't fit the bigger valves. Apparently the ones that are available new are not very good compared to original ones.

On a flow rig the flow through the original 1.560" valves has been measured at 78.2CFM with 0.400" lift. With a similar head with 1.620" valves the flow is 89.7CFM which is good improvement.

Thanks John
