For cold adjustment I set them to .001" more than spec for hot adjustment. Then warmed up good, cooled down, warmed up again, cooled - then retorqued head. As for break in - I ran it easy the first 5 hours, light load. Heavy load the next 5 hours. Then used it normally and changed oil at 50 hours. Changed oil again at 87 hours (it had been a year since last oil change). Most mechanics I have talked to recommend to break in an engine just like you are going to use it. Of course go easy the first few hours to be sure things get their initial "seat." Owner's manual says to change after first 100 hours - I think that is a tad too long. I judge by what the oil looks like - not the actual hours. Short run times in cold weather make for dirty oil faster. A couple more things: If you put in a new cam and lifters, you need to run at around 1/2 throttle for a half hour to break those in. I cranked my engine without spark plugs in until I got oil pressure before initial start up just to be sure everything was getting oil. Good luck!
