H8049 Small Block V8 Metallic Ceramic Coated Long Tube Header

The Patriot Exhaust H8049 long tube header is built to enhance the performance of small block V8-powered 1967-1987 Chevrolet and GMC K-Series 4WD trucks. By utilizing a long tube design, this header optimizes exhaust scavenging to provide noticeable gains in mid-range torque and high-RPM horsepower. The headers are constructed from 18-gauge steel and finished with a durable metallic ceramic coating, which is polished via a vibratory process to create a hard, lustrous aluminum-like surface that is 60% more corrosion-resistant than unpolished finishes. Installation requires specific considerations, as these headers do not fit angle plug cylinder heads. Additionally, installation requires the use of a left-side air conditioning bracket, specifically part number H7608; however, 1979 and later vehicles equipped with short compressors may be compatible with the stock bracket. These headers feature a 3-bolt flange for collector attachment and include the necessary gaskets and mounting hardware for installation. Before finalizing your setup, note that these headers are intended for performance applications and rely on original engine and cylinder head port centerlines. Always verify your specific truck's configuration, as deviations from these specifications or the use of raised-port heads will likely cause installation issues.
