The stem seals on the intakes prevent oil from being sucked down the
valve guides. Especially important as the guides wear. They do
eventually crack and fall off. Many an oil burning engine has been
helped by replacing these. Fairly easy and can be done with the head in
place.

This most recent set of head I'm installing had valve seals on the
intake
valves.   Anyone see a need for these?  Or install something else?
