Hi Andy,
The "normal" thing is to fit seals to the INLET valve guides,
 Not heard of doing it on the exhaust side  *conf*
Some guide sets are machined to take Triumph 650/750 seals, if not its easy to do in the lathe

The inlet sucks ( oil down the guide )
the exhaust blows ( combustion gasses into the head )
No need to seal the exhaust.
