This listing is for a brand new set of screw-in rocker arm studs. Set includes 16 studs.

They are designed to replace the stock style press-in studs on small block Chevy V8 engines without having to machine the stud boss down on the head. Just pull the old studs and tap the holes to 7/16"-14 coarse threads.
