Isky has a good description of the process for degreeing a cam at
http://www.iskycams.com/degreeing.php. Another FOT mentioned using a
piston stop. Their Web page describes how to easily make one.
Have fun. If you're a fellow geek, measure the follower lift at 5 degree
increments and plot it on polar graph paper - very interesting to visualize
the valve overlap, accel and decel ramps, etc.
