Harley Shovelhead Lifter Block/Tappet Guide Screws, 12 Point 1/4-20 (1976-84)

Harley used an early hydraulic block and screw set from 1953-early 1976.   But in late 1976, a different block style and screw set was used.  In general. early blocks used countersunk mount screws with a 1/4-24 size and pitch.  However, late blocks used the 12-point, 1/4-20 screw set.   This is the late set.

NOTE--with respect to application, we used the term "in general" because there may be exceptions.  Specifically, Factory references show continued use of 1/4-24 countersunk screws on some FL models after '76.   And FX references indicate "cap screw" use from as early as 1971-'76 on the FX models.   Therefore, the best way to verify proper fitment is to review the machining of your cases for either 1/4-24 or 1/4-20 pitch.   Then select the correct block and screw set for those cases.
