Engine Porting Kit can help your engine generate more power

Build the best performance engine or restore like-new performance to your older powerplant using Eastwood cylinder head porting tools and accessories. When serious engine builders "blueprint" an engine, they'll "port" or smooth-off rough head castings around the intake and exhaust ports for smoother airflow. The engine can then "breathe" easier, resulting in greater power and efficiency. Not only can this engine head porting kit help your engine generate more horsepower and torque, but it will also improve fuel efficiency, giving you more miles to the gallon as you roar around a track or down the highway.

About Eastwood Engine Cylinder Head 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 mean 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 airflow. 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 imperfections more aggressively, use carbide burrs.
