The Cylinder Head of the Buick Skylark is a component that sits on top of the engine block, sealing the combustion chambers while allowing the intake of a fresh air fuel mix and expelling hot exhaust gases. The cast assembly is for spark plugs and valves. Further, with torque to yield head bolts, it evenly clamps for a tight gasket seal. In addition, the complete unit prevents internal coolant, oil, and compression leaks. Over the years, two main Cylinder Head materials appeared, the traditional cast iron and the lighter aluminum. Iron imparts rugged strength while aluminum Cylinder Head versions reduce weight for enhanced balance and dissipate heat more efficiently, allowing the same Skylark engines to run higher compression safely for added power. Whatever the material of the Cylinder Head, all rely on accurately machined ports and seats which suppress volumetric losses as reducing restriction is important for stronger acceleration. When the guides wear, the springs' energy weakens, or warpage occurs and cracks the casting, it can cause fluids to mix together or can burn a valve and leave a dead cylinder. For cost-effective restoration of factory performance, worn Buick owners should change the TTY bolts that have stretched and ensure the gasket is totally flat against the Cylinder Head surface. The design ideas led to reliable output without excessive mass in the Buick Skylark models.
