Though you can probably get by without it, we recommend buying Trick Flow’s cam degree supplement kit. It includes a height-adjustable dummy lifter and a base to mount the dial indicator. The remaining components I used are from Proform Parts’ 13-inch Universal Degree wheel kit. Pick a cylinder (it doesn’t matter which one) and use the spring compressor tool to remove the lash adjuster, replacing it with the dummy lifter from the kit. This dummy lifter contains a set screw you can turn with the supplied Allen key to raise or lower the height of the tip, changing the gap between the roller and the cam lobe. I set the clearance to 0.020 inch because, according to Trick Flow’s specs, collapsed lash adjusters (engine off, no hydraulic preload) should have between 0.015- and 0.025-inch clearance between the roller and the cam’s base circle.
