Also, bullet says not to use the lifter bore tool for measuring any cam specs. If roller, must use a lifter because of the wheel size. Mine are .810 wheels. Doing this does seem to get more accurate measures.
Uh-huh...couldn't agree more...that fancy looking CompCams tool caused me a massive headache as I attempted to degree my mild hydraulic roller. Eventually, degreeing off of an actual roller lifter got me the matching numbers.
