S&S Cycle 89cc Super Stock Cylinder Head Kit For Harley Twin Cam 1999-2005

S&S Cycle 89cc Super Stock Cylinder Head Kit

S&S Super Stock cylinder heads for Twin Cam style engines offer significantly improved flow over stock cylinder heads and can be used with stock H-D 88″ and 95″ pistons as well as with S&S Twin Cam style pistons. Because the stock Twin Cam Style head bolt pattern is large enough to accommodate a cylinder bore size of up to 4″, all S&S heads for Twin Cam engines use the stock bolt pattern. This means that S&S heads purchased for an 88″ or 95″ engine can still be used if a rider later upgrades to S&S 4″ bore cylinders.

Features:

• 89cc
• Readily bolts on and accepts most stock components except head bolts and some rocker boxes
• Stock rocker boxes will not work if S&S Cycle electric compression releases are used
• Rocker box gaskets only

Note: Large port manifold recommended but not required - sold separately.
