yes the smoking on startup puzzled me too, i tried fitting "knowed good" different heads on ours, thinking it might be the valve guide seals, but the poxy thing still did the same !
at the risk of sounding critical the bores should have a "matt" crisscross finish when you glazebust it, that glaze is a high carbon skin (carbon soak from the burnt fuel akin to case hardening i think) and if not busted fully the new rings wont bed in properly i think.
