Q & A

What's in the Box

Many rodders are looking to install Chevy’s powerful and efficient LS1 / LS6 Small Block V8 in their street rods, customs and classic trucks. These shorty headers can make those installations easier in a variety of applications, and help produce more power as well.

An oxygen sensor bung is included with these block hugger headers, but not installed, for those who want to keep the engine’s electronic fuel injection. Includes bolts, gaskets, and reducers.

Sorry we do not offer a tube to fit these headers. You would be best off having a local exhaust shop bending a tube for you or you can make one from some of the bends that we offer. We have U bends 91013867 or combo bends 91013896.

Part # 9300114 With possible variations between builds we do not offer a direct application. These headers DO require our motor mount adapter plates in order to obtain the necessary clearance under part number 91618016. Dimensions of the headers for measuring your application are as follows: From head surface to furthest out point of tubes is 4”. Top of flange to bottom of the collector is 11” Collector ring sits within 1” of the block and is located in the center of the two center exhaust ports.
