Description
A compromised exhaust gasket will cause vacuum leaks, unburned fuel, and erratic idle conditions that waste power and mask other tuning issues. This graphite gasket set seals the critical interface between your LT1/LT4 headers and cylinder head, ensuring complete combustion and reliable performance across the entire RPM band. OEM gaskets deteriorate with heat cycling—upgrading to a fresh, quality set is essential maintenance for any serious small-block build.
