Response to break in oil or not ? I vote no. Your experience ?

I know what you're saying on high dollar 427's in the last year I have done 2 427's with no problems, I use comp cam break in oil, one of the engines we pulled the inner spring for break in one not, the one we didn't did not have high spring pressure the other did, if the motor does not fire instantly that could be a problem, too much spring pressure can add to the problem, not running for 20 minutes at 2000 rpm without overheating can add to the problem.
You have to try to cover all bases for good results, I always stress at break in time, the more the motor cost the more I stress, on big money engines I double and triple check before startup, a couple of Beers seem to help also, good luck
