About This Product
If you have a set of S&S cylinder heads but aren't currently using compression releases, this S&S hole plug is exactly what you need. It is designed to securely plug the 9/16-20 threaded holes in S&S heads when the releases are removed or not installed. This ensures a perfect seal for the combustion chamber, preventing any loss of compression or exhaust leaks. It’s a small but essential piece of hardware for fine-tuning your engine configuration. Made to the high standards S&S is known for, this plug provides a clean, professional solution for managing your cylinder head features.
Manufacturer part number: 90-4916.
