GM cylinder heads and head parts

Genuine GM and Chevrolet Performance cylinder heads, assembled and bare, with the valves, springs, seals, guides and head bolts for LS, LT, small block and big block engines.

What is here

Assembled cylinder heads for the LS3, LS7, LT1 and LT4 and the truck engines, Chevrolet Performance Fast Burn and Vortec heads for small block builds, bare castings, valve springs, retainers, seals and multi layer head gaskets.

Before you order

Heads are sold one side at a time on most engines. Check the casting and the valve size against your block and pistons, and order new head bolts, which are torque to yield and not reusable.

Why buy it from a GM dealer

GM heads are machined to the factory spec and flow tested in the design, so they match the intake and exhaust parts around them.
