1955-57 Chevrolet 265-400 Mctbc Ceramic Coated Oval Port Shorty Patriot Headers

These popular 1955-57 Chevrolet passenger car headers offer superior performance and are designed to clear most air conditioning, power brake, and power steering systems. Extra ground clearance makes "slammed" vehicles driveable and above frame rail ex haust system installation easy.

The Metallic Ceramic Thermal Barrier Coating (MCTBC) is simply the best header finish on the market and is available on all Patriot headers. MCTBC protects and extends the life of headers by creating a thermal bar rier that significantly lowers underhood temperatures and protects the substrate metal from thermal fatigue. After MCTBC is applied, it is polished with a vibratory finishing process that produces a high luster aluminum appearance. The polishing process c ompresses and activates the coating, which increases the surface hardness to produce a finish that is 60% more corrosion resistant than an unpolished surface. This coating is easy to maintain and will last for years under normal operating conditions.
