The intake seal has a defined "lip" that pressed against the valve, this limits the lubrication that the valve receives and if you are using cast iron guides it is a good idea to use the exhaust seal which will let more oil through. I only use bronze guides on street/race motors, so the extra lubrication is not necessary because bronze has it's own lubricating properties.
