Super Stock™ Cylinder Heads

Upgrade your engine performance with the Super Stock™ Cylinder Heads. Designed for high port flow, these heads ensure excellent performance now, and they are primed for future upgrades. Fully assembled with springs and valves, they offer a convenient installation experience.

Compression ratios vary based on your cylinder heads selection, pistons, and engine displacement. Refer to the Compression Ratios chart for detailed specifications. The 79cc heads are ideal for stock motors ranging from 88" to 103", while the 89cc heads excel in applications over 103" or with high-compression pop-up pistons.

Specifications include:

  • 79cc heads: 1.940" intake and 1.575" exhaust valves with springs capable of up to .640" lift.
  • 89cc heads: 2.000" intake and 1.605" exhaust valves with .640" springs.

These heads are machined for compression releases unless noted otherwise (sold separately), and require S&S rocker boxes when using S&S compression releases. Please note that rocker arm components, intake manifold, and gaskets are not included. The package includes four long headbolts and allows for the reuse of four long OEM headbolts.

Compatible with OEM intake manifolds and proudly made in the U.S.A. Please be aware that S&S rocker boxes (PART #90-4110) are necessary if S&S compression releases are utilized. Not compatible with Twin Cooled heads.
