Considering the valve spring seat pressure and Clark Kent'esque specs of the cam I figured a total of 15mins of break in were all that was needed. I put it through 3 x 5 mins break in cycles of 1800-2400 rpm under load. In between the 5 minute cycles was 10 minutes of cool down and inspection. I'm VERY paranoid when it comes to the break in period especially with a flat tappet cam and todays sub par manufacturing standards. Everything looked excellent during the break in with only a small valve cover leak onto the oil filter which took a couple turns of the vc bolt to cure. Who doesn't love the easy fixes?
I was able to perform 4 prelim pulls with the 4th up to 5800 rpm. Any guesses? J.Rob
