This kit is generally used with aftermarket aluminum heads with rectangular ports that require 12 bolts. For those with oval port intakes, you may require our 16 pc. kit. See part # I-150-16 in our other listings.

It is very important to use the extended reach intake bolts when using an aftermarket aluminum manifold and aluminum heads. All aluminum intakes have a much thicker flange compared to OE style cast iron manifolds. The common one inch bolts are not long enough when using any of the aluminum intakes on the market.

These bolts are made from pure 304 high grade stainless steel. The washers included are also stainless. These may also be used with cast iron manifolds, as there is usually sufficient clearance in most heads. Most aluminum heads have very deep threads and easily allow the use of the extended length bolts. The additional length on these bolts reduces the chance of stripping the threads out in the aluminum heads. Clamping is greatly improved.

Some intakes have over-sized mounting holes in them to aid installation, so you may want to add an over-sized washer. This will not be a problem due to the .25 extra length these bolts have. We use these exact bolts on every engine we build.

If you do run into a clearance issue due to the length of these, we do offer them in the 1.25 length. See our other listings.

5/16 ALLEN HEAD, 1.50" THREAD LENGTH

A PROPER SET OF INTAKE BOLTS.

These are what we use on most all the engines we build using aluminum intake manifolds. The allen head bolt eliminates problems encountered with hex head bolts when used on intakes.
