dropped a bolt in oil pan...
I didn't heat cycle my LS6 springs, but I did "take it easy" for the first 100 miles or so... I went on many short trips, but the engine never cooled completely. I think to REALLY heat cycle them you have to bring them up to operating temp at an idle, then let it cool completely 3 or 4 times. (But who the hell can wait that long after installing a new cam!)
