Tommy -
Valve guides would be one possibility. Another would be that you're
sucking oil vapor/droplets into the carbs through the PCV
(particularly any blue smoke on the "overrun", if you take your foot
off the throttle with the clutch engaged). How do you have the
crankcase ventilation hooked up?
Given the compression readings you've got there, I'd tend not to
suspect the rings, unless it's a fresh engine and the rings haven't
bedded in yet. If it's a fresh engine, give it time before you start
worrying.
