Recommendation:

If you are considering purchasing the Speedway 550806 Press-in Rocker Arm Stud Pinning Kit, ensure that it is compatible with your engine and that you have the necessary tools for installation.

Details:

Yes, I recommend this product. Most factory cylinder heads utilize press-fit rocker arm studs, which can pull out under certain conditions. Works with all engines using pressed-in rocker arm studs. Can be installed without removing heads from engine.

Keeps press-in rocker arm studs from pulling out. Includes 16 roll pins and 1 5/32 drill bit. These roll pins lock each stud in place, preventing them from rotating or loosening. Note: Not for engines that use hollow studs, such as early Pontiac V8s, have through-stud oiling the rocker arms.

Part # 550806 Condition New Brand Speedway Motors Sold Each Details Add positive retention to your rocker arms with this complete stud pinning kit. I just bought an extra drill bit. Stiffer valve springs, high-lift camshafts, high engine RPM, and overheating all contribute to stud failure. Had to buy a cobalt bit drill through the studs.

Headquarters. Great Product. Easy to install and fast.
