Cylinder Heads

Upgrading your cylinder heads is a great way to improve performance. You can decrease weight and improve flow. The cylinder head is an assembly consisting of the intake and exhaust valves, valve guides, valve springs, camshaft, and spark plugs. It is mated to the top of the cylinder, and forms the combustion chamber.

Cylinder Head Bolts

When doing a rebuild, or replacing the head, you should always replace the bolts holding the head to the block, as they have a tendency to stretch after they are torqued, which can cause numerous problems including blown head gaskets, loss of compression, and possible engine damage if a bolt head breaks off inside the valve train.

Cylinder Head Hardware

If you are at the point where you are working on the cylinder head you should finish it right by replacing the hardware with new.
