In order to achieve stated timing specifications, these cams must be used in engines with 1984-’99 style tappets.
These cams should not be ordered as replacement parts for early S&S SH-Series engines, or for any shovelhead engine equipped with stock valve train. For replacement
parts for these engines, select stock style cams and tappets.
S&S can do a special order cam, please contact your S&S customer service representative for more information
