【S&S Cycle 106-4277 Superstock Cylinder Head Big Twin (99-05) Silver Harley Engine Parts Protol】
■Product Description The S&S Superstock High Performance Cylinder Head is designed for 1999-2005 engines with stock crankcases. It fits engines with stock displacement but is ideal for slightly larger stroke or big bore engines up to 110Ci. The 79cc combustion chambers provide a slightly higher compression ratio than stock, making them perfect for high-performance cams. Machined for S&S compression releases. The large 1.940" intake valves and 1.575" exhaust valves supply ample air for slightly larger engines to reach their full potential, while maintaining port velocity for good low to mid-range response. S&S high-performance valve springs allow for camshafts with up to 0.65" lift. Compatible with stock rocker boxes, exhaust, and intake manifolds. ■Compatible Models: Harley-Davidson Big Twin (99-05) ■Specifications: Color: Silver Finish: Powder coat Included: Front & rear cylinder head assembly, rocker box gaskets, copper head gaskets, exhaust gaskets, hardware, instructions ■Notes: *Images are for illustration purposes only.
