5 Things to Check Before Buying a Cylinder Head – Clearwater Cylinder Head
Consider Intake and Exhaust Port Volumes – Bigger intake port volumes are not always necessarily better; depending on engine size and/or application, smaller intake ports may be more suitable. Smaller intake ports often provide better performance for street application as they produce more low-end torque and crisper throttle response, while larger intake ports are more beneficial for larger or higher-revving engines as they allow for more air flow. Choose a good-flowing exhaust port that is the correct size, by comparing to stock exhaust port volume and valve size for your specific engine.
Determine the Combustion Chamber Size and Design needed for Your Engine – Choose a combustion chamber size that raises the compression ratio to maximize your engines efficiency, while matching the components of your specific engine, such as, bore, stroke, head gasket, and piston shape, as well as, deck clearance and ring location.
Consider Application – Whether you are using your car for street or off-road driving or drag, circle track, or road racing, deciding the primary application for your engine is important is picking out the cylinder head to best fit your needs. Valve lift, air flow, and duration can be altered to provide the best performance for your car’s specific application.
Can You Repair a Cracked Cylinder Head?
The cylinder head is a vital part of many internal combustion engines. Along with a head gasket and rubber grommets, it seals the cylinders of the engine, ensuring its fuel intake, combustion, cooling and lubrication are all in working order.
One of the most important first steps in cylinder head repair is determining what piece is damaged, as this could mean the difference between a simple, decisive repair and a problem going unnoticed, only to require even more costly repairs when that problem worsens.
