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? Eric
