I am about to oversize my turbo engine and I have a set of +30 pistons. Which is the ideal valve size (for inlet and exhaust)?

Thanks guys

30mm Exh valves are unavailable from Minispares unfortunately. 31mm exhaust valves with hardened inserts (lead free Rover heads) is not ideal either. Better stick to 29,4 or make your own 30mm ones.
