Basic porting, while somewhat time consuming, is not hard work. Most of the work in a basic porting project is focused on reducing those restrictions which are caused by: 1) "steps" that may obstruct intake air flow as it transitions from the intake manifold to a smaller intake port entry in the head 2) casting bumps, ridges or other marks, such as those you may find on port floors or roofs 3) sharp edges, such as those you will find around the valve guide bosses at the top of the valve pockets and 4) the point where the intake port floor curves down to the valve seat. If you have more air, you can add more fuel. ![]() Reduce that restriction and you let more air into the cylinders. Why is basic port work important to your engine's performance? It reduces the restriction in the engine's intake and exhaust tracts. Once your porting project turns to that, you're beyond the scope of basic porting techniques. Basic head porting, however, is easy.so easy that even beginning hot rodders can do it well. Doing full-on race heads requires the services of an experienced cylinder head professional, so Pro Stock, NEXTEL Cup and similar heads are best left to experts. There is a significant difference between basic head porting for a streethigh-performance or weekend racer application and the very complex cylinder head work you see in a Pro Stock drag race motor or a NASCAR NEXTEL Cup race engine. 260005) from the Standard Abrasives Motorsports Division, along with a die grinder and some common hand tools. These basics can be done by any do-it-yourselfer, even those with no porting experience, using the Deluxe Porting Kit and the Gasket Removal Kit (part nos. ![]() Here's an interesting head porting fact: In many cases, the greatest performance gain per dollar spent comes upon application of basic porting procedures to a production cylinder head. In this cutaway of a production cylinder head, the short side radius has not one but two very sharp edges. Called the "short side radius," it is also a place where sharp edges and roughness pose a threat to flow. A more significant point of restriction is where the intake or exhaust port floor curves down to meet the valve seat. There are enough abrasive materials to port a set of V8 heads. The components of the Porting Kit are neatly packed in a compartmented box. A basic porting project seeks to smooth those sharp edges. The area of the valve guide that protrudes into the intake or exhaust port is always a place where sharp edges and restriction to flow are found. Basic porting does not attempt to correct any design or engineering deficiencies. Basic cylinder head porting will improve the performance of any production cylinder head by removing flaws that come through mass production. Basic Porting Will Improve Your Engine’s Performance. ![]() All you need is the Standard Abrasives Deluxe Porting Kit, some common tools and some free time.
