Description
Set of 16 high quality RAS5 (longer then RAS4) 190,000 psi 7/16 rocker arm studs AND a set of 8 5/16 push rod guide plates
See my other listings for stock length 7/16 rocker studs
I’ve been using these studs and guide plates on my high end Pontiac engine builds for many years. Studs are the same length as the weaker 3/8 factory screw in studs. Its silly to use those anymore (if you can find good ones!)
The guide plates are highest quality hardned steel for the factory 5/16 pushrods.2 plates replace one of the discontinued factory guide plates – they fit perfect every time!The studs are designed for guide plates and have a unthreaded area under the nut that locates the guide plates
Used on most Pontiac D-port heads that have stock valve lengths.
See my other auction for the longer stud version See my other auction for the 3/8 guide plates (not usually used on D port heads)See my other auction for just the studs
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
