Conversion Headers
for the
Chevrolet Small Block V8, Generation I & II
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 for nearly all models of Jeeps.
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.
Coated or Natural Steel
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.

Best fit for most Jeeps. The original Small Block is compact and these headers compliment that and work well in most all applications.

Installation Requirements
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.
Spark plug boot clearance provided
The short, block-hugging design allows the installer to have the exhaust routed in one of the following three popular ways:
- One circuit under the oil pan, just in front of the sump merging into the opposite circuit which is typically run rearward on the side of the Jeep opposite that of the drop of its transfer case.
- As above, but under the bellhousing slope.
- As above, but behind the transfer case. Then, the exhaust tailpipe can exit the Jeep on either the driver's or passenger's side.
