Small Block Chrysler 318-360 179cc Aeroflow Performance Aluminium Cylinder Heads with 63cc Chamber (Pair)

Aeroflow has become synonymous with premium quality performance products. Aeroflow's objective has been to incorporate state-of-the-art manufacturing, aerospace quality materials and rigid quality controls to produce quality performance products at extraordinary value. Aeroflow has taken its forward thinking knowledge to the street, manufacturing a wide range of race quality products to improve street performance and dependability.

The cylinder head sits on top of the engine and seals the top of the engine’s cylinders creating the combustion chamber – the place where the fuel and air mixture is burned. The passages in the cylinder head – known as the ports, allow for air and fuel to flow into the cylinder and exhaust gases to flow out of it. The head also channels coolant into the engine block, cooling down the engine components. It’s also the housing for the valve gear, springs, lifters, and spark plugs.

Most OEM cylinder heads are made from cast iron which is durable and cheap to manufacture, but heavier and not efficient at dissipating heat.

The Aeroflow Performance aluminium cylinder heads utilise high-quality ultra-smooth A356-T6 aluminium castings and new as-cast runner and chamber designs that produce increased power & torque, improved efficiency, and excellent flow numbers.

Designed for both street and race performance engines, the 5-angle competition valve job, diamond-honed bronze guides, hand bowl blending and professional assembly help the Aeroflow series of aluminium cylinder heads to outperform some of the best brands in the business.

The 179cc cylinder heads are ideal for operating in the idle to 6500rpm range.
