Cylinder Heads
The Role of Cylinder Heads

Internal combustion engines are, simply said, air pumps. The more air you pump into an engine, the more air/fuel you can burn, and the more power you can make. Building horsepower is not quite as simple as that, but it's the basic concept. The cylinder head
is the main component that flows air/fuel in and exhaust gases out. Needless to say, the cylinder head is a major component in building horsepower and torque. Because the way the shape and size of the combustion chamber affects so much of an engine's
operation, you have to choose the appropriate selection, not just the one with the best peak numbers. Understanding cylinder head terminology and ultimate affects, will lead to a better choice for your application. Your goal should be to choose the best heads
for your application. Going with the BIGGEST heads, is not always best.

Cast Iron Cylinder Heads

OEM cylinder heads are often cast iron which offers durability and a lower cost to produce and manufacture. Cast Iron heads, as you would expect, are also heavy. For almost all applications, lighter is better. Drag cars in particular benefit to help transfer at
launch and road course/ circle track cars benefit from better weight distribution. Another downfall of cast iron is it lacks the ability to dissipate heat. Aluminum dissipates heat better, which will allow for a higher compression ratio without detonation. Cast iron
will provide a good option for the budget minded builder. Performance options are available for cast iron heads that include larger valves and increased flow designs, but should be limited to lower compression street cars for the most part.
