These S&S® Super Stock® high performance cylinder heads are designed for 1999-'05 engines with stock crankcase. They work well with engines of stock displacement, but are ideal for somewhat larger stroker or big bore engines up to 110". The 79cc combustion chamber provides a slightly higher than stock, which makes most performance cams work better. Machined for S&S® compression releases. The large 1.940" intake and 1.575" exhaust valves maintain port velecity for good low and midrange response, but supply enough air for stock and slightly larger engines to perform to their full potential. S&S® High performance valve springs allow the installation of camshafts with up to .585" lift. Compatible with stock rocker boxes, exhaust, and intake manifolds. Wrinkle black powder coat finish matches stock black engine components.

  • High port flow gives great performance now, and more later when additional upgrades are done
  • Heads are fully assembled with springs and valves
  • Compression ratios vary depending on cylinder heads chosen, pistons used and engine displacement; see Compression Ratios chart for specifications
  • 79cc heads work great with stock motors for 88" to 103" motors; 89cc heads work best for motors over 103" or with high-compression pop-up pistons
  • 79cc have 1.940" intake and 1.575" exhaust valve and springs for up to .650" lift; 89cc have 2.000" intake and 1.605" exhaust and .640" springs
  • 79cc heads accept OEM rocker boxes
  • 79cc and 89cc heads require S&S Lower Rocker Box Gasket Kit (0934-4574)
  • Heads are machined for compression releases (sold separately); S&S rocker boxes required when using S&S compression releases
  • Do not include rocker arm components, intake manifold or gaskets
  • Heads include four long headbolts, and reuse four long OEM headbolts
  • Accept OEM intake manifolds
  • Made in the U.S.A.
  • Must use S&S rocker boxes (PART #90-4110) if S&S compression releases are used.
