Product Details

If you're working on a classic Oldsmobile with a 400, 425, or 455 V8 engine from 1965 through 1976, these exhaust gaskets from Edelbrock are what you'll need to seal up your exhaust manifolds or headers. They're built to handle the heat and pressure that comes with these big V8s, ensuring a tight seal that won't leak exhaust fumes.

These gaskets are constructed from Edelbrock's EnCore HTX-900 material. It's a well-built composite that combines graphite-coated, heat-resistant fiber sheets with a mechanically and chemically bonded expanded steel core. This construction gives them excellent load retention and the ability to seal effectively, even if your header bolts loosen up a bit. They have a 50% recovery rate, meaning they can expand to maintain a seal if your header torque fluctuates. The port size is 1.95 inches by 1.56 inches, which is a common size for these Oldsmobile V8 applications.
