Product Description

7/16" Screw In Studs
Fits: Pontiac w/ screw in studs

These are intended to replace factory "bottle neck" screw in studs used in select Pontiac engines. Mostly 400 and 455 engines.

If your Pontiac has screw in studs with a "necked down" type step stud on the topside, they can be replaced with these 7/16" studs. Just unscrew the OE factory studs and replace with these 7/16" studs.

If you have roller rockers which come with 7/16"NF poly locks, they can now be used with these 7/16" studs.

If your roller rocker set comes with the smaller 3/8" poly locks, they'll need to be replaced with the 7/16" version which is a more durable set up.

Not for Pontiac's w/ pressed in studs. They must be threaded to 7/16"NF to use with these.

These are good quality studs suitable for high spring pressure, high performance applications.
For those who want to reuse their stock rockers but want to convert to a fully adjustable rocker set up, we also offer a special conversion kit which comes with new 7/16" rocker studs, new grooved rocker balls and new crimp style adjuster nuts. Check our other Pontiac parts or write. Parts are available now!
Be aware that some of the 60's Pontiac's have 1/2"-13 NF base threads in their heads. Heads with 1/2"-13 threads have most likely been previously modified as very few of the early engines had screw in studs from the factory. If you have an 389, 421 or other early Pontiac which has screw in studs so be sure to verify they have 7/16" base threads.
