The metro turbos in the mg cup these days are only allowed std size valves.
If its the old 1980's challenge car I should think they are pretty big

depends who you ask or believe .. could be 35.6/29 and 27cc or some were 33/33 valves

Everyone knows that instructions only have to be read if the thing doesn't work....
