I've had these gaskets for 15 years and they have performed flawlessly. Never loosened, never leaked. I recently had the engine out of the car and replaced the inserts when I re-installed the engine. I got the replacements from Summit. One thing to watch, The on-line catalog shows 8 inserts, but when they arrived, the package had only four. They sent me the additional 4 inserts at no cost. Summit Racing is a class act.
