IMPORTANT NOTE: Hydraulic Roller <strong>Cams</strong>hafts are designed to be<br />
used with a Ford stock length valve. Failure to do this will<br />
give incorrect gross lift, incorrect rocker geometry, and cause<br />
premature wear and loss of power.<br />

IMPORTANT NOTE: Mechanical roller cams must use a valve that is<br />
4.900” overall length, such as a small block Chevrolet valve.<br />
There should be .300” from tip of valve to top of keeper<br />
groove. This valve combined with <strong>Crane</strong> springs, retainers<br />
and locks will enable you to obtain proper valve spring<br />
assembly height and give you a .090” cushion from coil bind.
