Cams for 318's

I've run the factory dog-bone style roller to .638" and 6700 rpm in a 365 that makes about 500 hp. As far as I know it is still going. Keep in mind though that was 2011 and I have had hydraulic lifter problems ( across all brands ) since about 2013. J.Rob

anyone with hard data on stock or iron rockers?
