i like the break in oil in the flat lifter cams longer as well as i like street stuff broke in on strait weight there not getting loaded on a dyno so i feel 800 or so miles will not hurt . i could get away with less i am sure with TQ plate hone and ultra plateau honed walls just feel better this way .every one has there way alot of the race stuff only see.s 20/50 weight race oil i have guys only run them in just like that it has some zddp and is a roller cam stuff
