Overall Assessment

Customers appreciate this high-quality product for its perfect fit and easy installation. Offering great value for the price, it's commended for its solid parts, quality finish, and strong, durable nature. Many confirmed it's superior to original cork gaskets. Reviewers recommend using studs over bolts during installation. The product particularly stands out in its high-performance use in big block Corvettes. No additional gasket sealer is needed due to its excellent sealing capability. The stainless core ensures the gasket stays in place during the installation, making it particularly user-friendly. Overall, these top-rated valve cover gaskets have exceeded customer expectations.

Why counter sunk around bolt holes?

Good quality gaskets seem to seal up but not sure why they seem to be cut out at half the depth around the bolt holes. Seems like that makes them harder to seal.
