The Mopar "LA" 318 & 360 V8's have become more popular for some Jeep engine conversions and our headers, with their compact design, make installation and engine positioning an easier task.
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 1-1/2" primary tubes with a 2-1/2" three-bolt style collector. The headers are a medium length, measuring 12" & 13" 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 headers will work with nearly all major Mopar Dodge “LA” 318 & 360 V8 engines.
Best fit for most Jeeps 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:
