From WebCam: Please use a premium grade (SAE 30) petroleum-based racing motor oil such as Kendall or Valvoline. We do not recommend any type of synthetic oil. Use new followers, shims, rockers, etc. with new camshafts. Failing to do so will cause premature failure of your camshaft. Camshafts require special break-in procedures. For the first 10-15 minutes of use, we recommend setting your engine at a high idle (2000 rpm) to insure proper lubrication.

PLEASE TAKE CARE DURING INSTALLATION. THERE IS NO LOBE WEAR OR BROKEN BILLET WARRANTY.
