My two thoughts on this.
One - how many passes were on the valve springs? Were they allowing the lifters to bounce/skid? I change valve springs every winter. It just seems like cheap insurance to me. My cam is not as aggressive though. 683/683 284/288@.050
Two - I run heavy oil and an additive. I use Lucas 20w50 and comp cams break in lube with every oil change. Maybe I am giving up hp and et by doing this, but I have been 9.45 @140 in NSS trim weighing 3585. Light weight oils just are not worth it to me.
