We fitted an access plate to our stock timing cover, which allows access to the adjustable cam gear of our Comp timing set. With lightweight checking springs installed on the number 1 cylinder, the cam was degreed-in and the valve-to-piston clearance was checked. We set the cam at 108-degrees intake centerline, which is four degrees advanced in regards to our 112-degree lobe separation cam. We were pretty tight on valve-to-piston clearance, and although a 108-degree installed centerline provided just enough clearance, we were unable to advance the cam any further without getting dangerously close on the intake valve.
