Trick Flow® High Port® 225 Cylinder Heads for Small Block Ford
Trick Flow® High Port® 225 cylinder heads are specifically designed for large cubic inch small block Ford engines as well as engines with high-boost superchargers or turbos, big shot nitrous oxide systems, and other mega-power combinations.

Summit Racing™ Pro GPX Gas Ported Piston Rings
You may have heard of gas ported pistons in high-end racing engines. Summit Racing™ Pro GPX gas ported rings add this performance to ANY non-gas ported (or even gas-ported) piston. They are also a great way to juice up cast and hypereutectic pistons for little extra money. How do they work? With a series of perfectly oriented slots on the top side of the top piston compression ring, the combustion pressure reaches the inside the ring groove and fully activates the ring sooner and longer for better seal. This not only makes more horsepower; it dramatically reduces blow-by and reduces or even eliminates the need for a catch can. Other benefits? Because the rings are always rotating and directly exposed to the detergents in the oil, these ports stay clean without carbon buildup that fouls out gas ported pistons over time for longer term performance. Since the rings are only activated at high pressures and no part of the cylinder sees the load repeatedly, the engine will last a long time. Nearly all our Summit™ GPX gas ported rings use top-tier nitride steel top rings, ductile seconds, and premium quality stainless oil rings. Better yet, we have them in nearly every popular bore and thickness for virtually any brand or configuration on the market. If you want to pick up power and performance, Summit Racing™ Pro GPX gas ported piston rings are the new standard at a great value!

Total Seal Gas Ported Piston Ring Sets
Total Seal gas ported piston rings feature strategically sized and placed horizontal slots in the ring. This allows combustion gases to enter through the groove and behind the ring to gas-load the ring—providing greatly improved ring sealing. No matter which type of racing your engine is designed for, it will benefit from the additional ring sealing. The benefits? Increased power and increased engine oil life! Order the piston ring set recommended for your engine application.

Chevrolet Performance LS9 CNC-Ported Cylinder Heads
Chevrolet Performance LS9 CNC-ported cylinder heads represent a new benchmark in factory engineering high performance, blending the strength and durability of the production LS9 cylinder head castings with the airflow enhancements of precision CNC porting. The result is about 10 percent more efficiency than the production casting, while delivering the greater strength built into the LS9--Rotocast from super-strong A356T6 aluminum alloy. With the Rotocasting method, the mold rotates to more evenly distribute the molten alloy, creating a denser casting that virtually eliminates porosity. And compared to the similar LS3 heads, Chevrolet Performance LS9 CNC-ported cylinder heads feature reinforced webbing and a thicker deck for greater rigidity and minimal distortion. The A356T6 alloy also manages the higher heat of a forced engine more effectively. The heads come fully assembled with production, lightweight titanium intake valves, sodium-filled exhaust valves, and strong beehive-type valve springs that can handle up to .570 in. lift and can be installed on any LS engine with at least a 4.000 in. bore using standard 11mm head bolts.
