What size exhaust primary pipe do these gaskets fit?

These Cometic header gaskets are designed for exhaust headers with 1 3/4 inch primary pipes. This size is common on many performance exhaust systems for the Ford 302 and 351W engines.

Do I need to use RTV or any other sealant with these gaskets?

No, these Cometic HT header gaskets are designed to seal effectively on their own without the need for any additional sealants like RTV. This helps ensure a clean installation and a reliable seal.

What is the thickness of these header gaskets?

The gaskets in this set are .060 inches thick. This thickness is often used to help achieve a good seal, especially if the header flanges have minor imperfections.

Product Details

This set gives you the header gaskets you need for your Ford 302 or 351W engine. Specifically, you get a pair of .060 inch thick gaskets designed for 1 3/4 inch primary exhaust headers, fitting 1973, 1979, and 1985-1993 Ford Mustangs. These gaskets are made to seal well without needing any extra sealants, making your installation cleaner and simpler.

Cometic builds these gaskets with their HT material, which is known for its ability to handle the heat and vibration common in exhaust systems. The .060 inch thickness is a common choice for header installations, helping to ensure a good seal even if your header flanges aren't perfectly flat. Because they don't require additional sealants, you avoid the mess and potential for leaks that can come with them, ensuring a solid seal right out of the box.
