Copper collector gaskets are the answer to help prevent persistent leakage at the header collector.
Unlike composition fiber or combination fiber and metal gaskets, copper expands and contracts with the temperature of your cylinder heads. Since copper is soft, it compresses to form a better seal to begin with, and it won't burn out! Copper gaskets have been used in aviation applications for years, and now they're available for automotive use with your Sanderson headers.
Our collector gaskets are manufactured from 0.062" thick dead soft copper, and can be annealed to return them to their original thickness. In other words, "They Are The Last Gaskets You Will Ever Need To Buy!"

Use the image below to make certain you order the correct size collector gaskets for your headers.
TECH TIP :
Header collector gasket sealing will only be as good as how well you have secured the rest of your exhaust system behind your headers. If your exhaust pipes and mufflers are swaying back and forth with every motion of your vehicle you are going to strain the sealing accuracy of your collector gaskets and your header flanges. Please be certain to use proper hangers that secure your exhaust piping which will provide you with years of trouble-free, accurate sealing.
