S&S Super Stock Cylinder Heads For Harley Twin Cam

Enhance your vehicle's performance effortlessly with these heads, compatible with both stock and aftermarket pistons. Ideal for those seeking additional power without extensive modifications, these heads simply bolt on for immediate impact. Although they perform well with stock parts, pairing them with a quality exhaust system, air cleaner, and a more aggressive camshaft will maximize their potential, thanks to the high-lift springs installed by S&S. While not mandatory, adjustable pushrods complement these upgrades well. Remember to include gaskets in your setup.

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
