New stock length 7/16″ Screw In Rocker Arm studs for Pontiac 400 428 455 D-ports
$ 40.50
- Description Set of 16 high quality 190,000 psi 7/16 rocker arm studs. I’ve been using these studs on my high end Pontiac engine builds for many years. These are the same length as the weaker 3/8 factory screw in studs. Used on most Pontiac D-port heads that have stock valve lengths. See my other auction for the longer version of these Requires 7/16 poly locks and manual adjustment. The adjustment is same as Chevy small block and there are many you tube video’s and google searches to perform this task. Buy in confidence! Spotts Performance has been building and selling Pontiac V8’s since the late 70″s
