The shorter ones are intake, the longer ones are exhaust. The seals are marked with letters: IN for intake, EX for exhaust. If the edge casing position is flat, it's an intake valve seal; if the edge casing has a protruding rim, it's an exhaust valve seal. Gray indicates intake valves, black indicates exhaust valves.
