There are plenty of header options for the most famous engine of all time, but after many years and many Jeep conversions, we've narrowed our favorites down to these block-hugging, short style headers for the Small Block V8 in all models of Jeeps.
For Conventional Small Block Heads
The header starts with a generous, 3/8" thick manifold flange. A patented port-seal surface is face ground at the mounting face of the engine head such that they can be used without a gasket (see installation notes below for more information). Headers feature 1-5/8" primary tubes with a 3" three-bolt style collector. The headers are short, measuring 8-3/4" from the center of the head flange to the bottom of the collector.
Included are Left and Right headers, header-to-head bolts along with instructions. Gaskets and collector bolts are not included.
The basic header is offered in natural steel, which the customer can optionally have finished in a variety of hi-temp enamels or other finishes that will offer rust protection and good appearance.
The best thermal and corrosion protection for your headers is our Aluminized Ceramic Coating. This finish offers the added benefit of lower under-hood temperatures and the highest level of protection to the header.
These are designed to fit the Classic Small Block Chevrolet engine 1955 and up. Two styles are available for spark plug clearance on standard and angle plug heads. Will not work with LS style engines.
Best fit for most Jeeps. The original Small Block is quite forgiving with its exhaust and these headers work well in most all applications.
Recommended installation to the engine is high temperature RTV such as Ultra Black® without a gasket. We have found this works exceptionally well. Some have used the original equipment type MLS (multi-layer steel) gaskets with good success. Collector gaskets and bolts are not included with the headers. We recommend using solid copper gaskets to avoid blowouts at that joint. Instructions are provided with the headers.
The short, block-hugging design allows the installer to have the exhaust routed in one of the following three popular ways:
