Collection: Cylinder Heads
Cylinder heads are vital components of the engine that sit on top of the engine block & house the intake & exhaust valves, spark plugs, & other critical parts. They play a crucial role in the combustion process by sealing the combustion chambers & allowing the intake of air & fuel & the expulsion of exhaust gases. Cylinder heads are typically made of cast or aluminum alloy & undergo precise machining to ensure proper fitment & performance. They are designed to withstand high temperatures & pressures generated during engine operation. Cylinder heads can vary in design, including single overhead cam (SOHC), dual overhead cam (DOHC), or overhead valve (OHV) configurations, depending on the engine design. Over time, cylinder heads may develop issues such as warping, cracking, or valve seat wear, which can lead to decreased engine performance, coolant or oil leaks, or overheating. In such cases, repairing or replacing the cylinder head is necessary to restore engine functionality. Proper maintenance, including regular inspections & timely repairs, is essential to ensure the longevity & efficiency of the cylinder heads & the overall performance of the engine.
