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.

These head porting tools are trusted by both DIYers and professionals for their engine builds or rebuilds. Each kit comes with 40 80-grit abrasive rolls (both tapered and cylindrical), two 4-inch mandrels, two 6-inch mandrels and complete instructions. You can finish both heads in one evening simply by following the instructions or watching our informational video. We’re here to help you Do the Job Right on all engine projects.
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.
- Forty 80-grit Abrasive Rolls (20 tapered and 20 cylindrical)
