IMHO...if you want to eliminate all your worries about breaking in the cam...go with a roller. The controversy regarding flat tappet cams going flat has gone on for years. I had the front 4 lobes on my L72 427 go flat after I took all the precautions such as removing the inner springs, putting in oil addative, starting immediately etc. Good luck.
