APE heavy duty cylinder studs for the CB500 & CB550.
Heavy duty cylinder studs are necessary to prevent head gasket leakage in high compression engines. Stock studs are made from poor material that will stretch and allow gasket leakage. APE studs are made from heat treated chrome moly, centerless ground, and have rolled threads after heat treat for maximum strength. APE originated heavy duty studs for performance motorcycles and today is recognized as the industry's leading manufacturer. We supply studs to all of the top engin builders. No matter whose parts you have in your engine, join the top names in racing and insist on APE studs to hold it all together.
There are 2 different size studs.

Faulty metal
I had one shear off before reaching the manual specified 16 ft/lbs of torque. These are the ONLY bolts available though, so I guess you'll have to try your luck. I am now contemplating buying a second set form here just to replace the one broken stud.
