    55 – 80 Corvette Ceramic Coated Ramhorn Manifold Replacement ! 1 5/8 to a 2′ Collector

    Sales of our McJacks Patented, Big & Small Block Cast-Iron replacement Headers are currently on hold until further notice. Our Exclusive Patented Design has been a great seller for McJacks as our headers allow you to replace your worn-out factory cast-iron manifolds and just bolt on our Small or Big Block headers… and you’re done. No exhaust work needed ! Price Hikes across the industry have forced us stop production and look at our options going forward.  There should be enough pieces in the short-term on the internet, if you’re still looking. For now, I will still be painting and restoring C1 and C2 Corvettes !   1955 - 1980 Corvette Ceramic Coated Ramhorn direct replacement Headers with inside Copper Coating for Cooler Engine Bay Temperatures. You won't find these headers anywhere else as they were developed, and are made here at McJacks Corvettes. As you can see these are direct replacement for the old Ramhorn Manifolds that GM has been making forever. These are 1 5/8' 16 guage mandrel bent tubing to a 2' Collector. These will give you more power, and only found here at McJacks
