I had my guides cut for seals and the exhaust valves replaced with valves with a smooth stem....... no step.I would replace the seals but on the stock heads you can't replace the seals on the exhaust valves as there aren't any...
bottom end/heads have 64k miles
I too got tired of the oil burning in the exhaust.
