JE Pistons Tour Series Gas Ported Pistons

JE Pistons Tour series gas ported pistons have undergone engineering changes to handle higher horsepower 4-barrel applications (approximately 650 hp) and angle-milled heads. Both the 350 and 400 Series accept oversize valves (the intake pocket is 2.255 in. and the exhaust pocket is 1.870 in.) and long-duration, tight lobe separation cams. Ring grooves are precision-machined for .043, .043, 3.0mm backcut rings with lateral gas ports for a superior ring seal.

AFR 357cc Magnum BBC Cylinder Heads

If huge horsepower is what you are searching for, AFR 357cc Magnum aluminum cylinder heads will certainly deliver. With AFR's fully CNC-ported 357cc heads flowing 425 cfm, they represent the ultimate in airflow for your big block Chevrolet.

AFR 357cc Magnum BBC cylinder heads will work best with camshafts exceeding 0.750 in. gross valve lift to make better use of the substantial airflow found in the higher lift range. The AFR 357cc heads come standard with AFR's trademark 3/4 in. thick cylinder head deck, reinforced rocker stud bosses, and premium one-piece stainless steel 2.300 in. intake and 1.880 in. exhaust valves.

Inspired by Dart's championship winning Pro Stock designs, Dart Pro 1 aluminum cylinder heads cover a wide range of applications from street cars and trucks to all-out racing. Heads designed for street performance and mild bracket racing offer excellent mid-range torque and power, and are excellent for heavier vehicles. Competition heads are ideal for maximum effort naturally aspirated, big boost forced induction, or nitrous applications. Dart Marine Pro 1 cylinder heads feature an exclusive chromate surface finish to inhibit corrosion and extend the life of the head. They are also fitted with Inconel exhaust valves to withstand the extended running time and temperatures typical of marine usage. Dart's as-cast ports flow more than many ported designs at a much more affordable price. But they also offer fully CNC-machined heads with every intake port, exhaust runner, valve bowl, and combustion chamber shaped by their 5-axis, computer controlled machining centers to produce compound curves and complex shapes that no human could duplicate with a hand grinder. Available bare or fully assembled, long-wearing bronze valve guides, screw-in studs, multi-angle intake seats with hardened, radiused exhaust seats are standard on most heads. Assemblies typically include stainless steel valves, premium springs, locks, retainers, guide plates, and seals. Many Pro 1 heads include race-proven features such as improved spark plug location, extra-long intake valves, raised exhaust ports, and fast burn chambers. They are offered an extensive variety of valve angles, intake port volumes and shapes, exhaust port locations, valve sizes, and chamber volumes.
