"screw-in" rocker arm studs and flat guide plates for various (non-LS) Chevrolet small block V-8 engines; 265ci, 267ci, 283ci, 302ci, 305ci, 307ci, 327ci, 350ci, and 400ci. P/N RDS-941K + GP-100K.

We recommend using these studs with "stock" appearing rocker arms. If using full roller rockers, we recommend using a longer rocker stud.
