Well everyones experience level is different and I don't have leaks and have been very luck with cams as well and if it was on a stand I'd still have to remove it and fix it,so it gets broken in in car style and if there ever is a leak I'll be pulling it.LOL I run it 15 or so minutes keeping the rpms between 1500-3000rpm ,while checking/setting the timing ,then I simply slide inside put it in gear and bring the engine up against the converter several seconds at a time. After 30-40 minutes I remove the filter,cut it open and have a look,when satified that all is well I simply install a new filter and take it for a few passes at the track or my favorite out of the way test course. Change the oil and filter after a couple of races(10-20 passes) and enjoy.
