camshaft break-in

I asked a lot of the same question you did. And over and over people and Comp cam told me to take the springs out. So I did. Made sure everything was straight before start up because you don't want to have to shut it down half way though. I used a high zink oil plus comp cams break in additive. Fired it up, once it running ramped it to 3000rpms until it comes to operation temp 180+. I let it run for nearly 20-25 minutes like that. Than I shut it down. And put it away. Next day changed the oil and filter. Next I installed the inner springs. I purchased the right tool to use with shaft mount rockers. Cost me like $50, worth every penny. Swaping out the springs went so smoothly. Then it was ready to rock.
