These Summit Racing™ exhaust gaskets are made from thick copper, and feature an embossed ridge around the exhaust port for a tight, leakproof seal.
The copper gaskets help even out the flow between the head and header flange to minimize warping.
Also, they'll conform to rough or irregular surfaces to maintain a positive seal, while keeping the header bolts tight.
