Re: Cam, Lifters, Headers In An Inline Six

I would measure the width of the key slot in the HB, then measure the crank key width to be sure the key isn't too small allowing the HB to "rock" back and forth against the key creating shock loads on the damper. It wouldn't take but a few thousands to allow the damper to move back and forth too much.
