Product Details

Super Stock™ Cylinder Head Kit (90-1106) by S&S Cycle®. 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 89cc combustion chamber provides a slightly higher than stock, but still manageable compression ratio in larger than stock engines. This makes them a good choice for touring bikes and other heavy vehicles. The large 2.000" intake and 1.605" exhaust valves maintain port velecity for good low and midrange response, but supply enough air for slightly larger engines to perform to their full potential. Accept 3-5/8" bore cylinders. Feature a stock like appearance, but flow much better than stock heads. Heads come assembled with premium valves and S&S® valve springs that can handle cams with lifts up to 0.590". These heads are machined for one spark plug per head. These cylinder heads are original equipment on S&S® SH-Series engines, and are a great upgrade for stock shovelheads. Rocker boxes are fastened with 5/16"-18 cap screws instead of the stock studs and nuts. KIt includes front and rear cylinder head assemblies, rocker box gaskets, copper head gaskets, exhaust gaskets, hardware, and instructions.

Notes
