Edelbrock SBC Exhaust Gasket

Edelbrock has been a name in performance parts for a long time, known for their intake manifolds and camshafts. Now, let's talk about their exhaust gaskets, specifically part number 7204. These are built for Small-Block Chevy engines from 1958 through 1986, covering popular displacements like the 302, 327, 350, and even the 400 V8. If you're working on a classic Chevy truck, Camaro, or Chevelle from that era, these are likely what you need to seal up your exhaust manifolds or headers properly.

What makes these gaskets stand out is the EnCore HTX-900 material. It's a composite that combines graphite-coated, heat-resistant fiber sheets with an expanded steel core. This construction is designed to handle high heat and maintain a solid seal, even if your header bolts loosen up a bit over time. They have a 50% recovery rate, meaning the gasket can expand to compensate for lost torque, helping to prevent exhaust leaks. The port size is a standard 1.50" x 1.50", which is common for many Small-Block Chevy applications.
