S&S Super Stock Cylinder Heads For Harley Twin Cam

Bolt on some ground-poundin' power. These heads are designed to be used with stock flat top or aftermarket pistons. You don't need crazy-master-engine-builder-status to make good, usable power - just bolt them in and go.  While they will work with stock components, a good exhaust, air cleaner, and cam will make these heads really shine. (You can go a little wilder with the cam, too - S&S installs high-lift springs for you!) As with most engine modifications on a Blockhead, adjustable pushrods are a great (but not absolutely necessary) addition to whatever package you're putting together. Don't forget gaskets!

Features:

• High port flow gives great performance now, and more later when additional upgrades are done
• Heads are fully assembled with springs and valves, and are available in silver or wrinkle black powder-coat
• Compression ratios vary depending on cylinder heads chosen, pistons used and engine displacement
• The 79cc combustion chamber provides a slightly higher than stock, which makes most performance cams work better
• 79cc heads work great with stock motors for 88" to 103" motors
• 1.940" intake and 1.575" exhaust valve and springs for up to .640" lift
• Heads accept OEM rocker boxes
• 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, gaskets or head bolts (requires eight long OEM length head bolts)
• Compatible with stock rocker boxes, exhaust, and intake manifolds
• Sold in pairs
• Made in the USA
