Conclusion

There are many different designs of exhaust manifolds for big block Chevy engines, but the most common style is the flowing big block Chevy exhaust manifold. These manifolds are designed to allow the exhaust gases to flow more freely from the engine, and they usually have larger diameter piping than stock manifolds.

The increased flow of exhaust gases can result in increased power and efficiency from the engine.
