My friend with an accord v6 did a 5 angle valve job, port and polish, stainless steel valves, and he had to resurface the head. When he installed it his car would make a loud whining noise and a big puff of white smoke would come out of his exhaust once he starts the car. He got rid of the whining noise, but the smoke still comes out everytime he starts the car. I know this has nothing to do with integra owners, but i was wondering if anyone knew what the problem could be. One more thing, I'm interested on doing the same thing since the LS/VTEC conversion is too risky. Also if i do decide to do the head work will i be able to pass smog? Thanks guys.
