Use the factory gaskets and go to NAPA and get a steel flange gasket. The paper gaskets will blow. Other than that, love them. Super easy to install.

This header was the answer to a lot of problems. I installed a Weber DGV on my MGB. I needed headers to install the new intake manifold. With the Weber kit and this header all my vacuum problems were gone. Very easy to install with no special tools or welding. Simple cut existing exhaust to correct length and bolt on. Heavy duty.
