Rated 5 out of 5 by from Easy I ported 2 heads and modified a eaton supercharger with this kit. I did purchase a single long reach carbide burr. Because the carbide burr did most of the work I only used 2 cones and 1 barrel out of this kit. If you have not done this before use this kit and it will take longer but will not allow you to have an oops as quickly as the carbide burr will. This is my first time doing this and I ported my first exhaust port with the drum and cone. It came out very nice. After that I was more comfortable with the air grinder and switched to the carbide burr, with the final touches done with the cone and drum from this kit. My recomendation is to buy this kit and one carbide burr. You may or may not need the long mandrels but they are definately nice to have. I used both and my carbide burr was a long reach. With this combination I am sure you will have some cones and rolls left over for other projects.

Rated 5 out of 5 by from Exactly what I needed. I purchased this kit to clean up what I had already removed when port matching my exhaust ports. These appear to just be rolls of sandpaper, but it made smoothing pretty easy. I only had to use a couple rolls on each head. I'd definitely say its worth the value.

Rated 5 out of 5 by from well worth the money and more Very good product. ..high quality for the price. ..i found that using my air die grinder and turning the regulator down to get it below 20,000 worked much better. Use a burr to do main shaping and this to polish it out and it doesn't get any better

Rated 5 out of 5 by from Great product I am very pleased with the engine porting kit 46056 from Eastwood.. The sand paper is of great quality and holds up well, great for smoothing the ports out with. And the 6" barrels are a plus,well worth the money.

Rated 4 out of 5 by from Great Product This is a great product for a great value. But its downfall is that it can not get into tight spaces very well. Used them to port my GM LS heads and was only good for large flat areas.

About Engine Porting Kit

Internal combustion engines are sophisticated air pumps that pull in an air/fuel mixture, compress it, ignite it, react to the ignition and expel the exhaust fumes. The better an engine pumps air, the more efficiently it will operate. This is one reason why we've seen a turn to multi-valve engines in recent years. More valves means more air moving through the engine. More air means greater engine efficiency – both more power and better fuel economy.

When you "port" an engine, you remove imperfections and restrictions between the combustion chamber and intake manifold and, therefore, increase air flow. This is done by 1) "smoothing" (or, grinding) the passages in the intake manifold so that they are the same size as the gasket and cylinder head, and 2) removing "rough cast" or "flash" imperfections in the cylinder heads and exhaust manifolds.

For best results use a high-speed grinder. To remove more aggressively, use carbide burrs.
