I have a set of S&S heads for sale. These are the 89cc that have been decked to 84 or 85cc( I cant remember)by Randy @ HYPERFORMANCE. Have had comp. release installed and are included. These heads are also the older style that can use the stock Harley Rocker boxes. They are used but in good condition I will have pics when I get them from my mech. I also have 95" SE cylinders and S&S pop up pistons still loaded in cylinders for sale. I will also be selling a VH Propipe that has had o2 bungs welded in. The propipe is used and has some scratchs and blueing. I also have a baffle with a nut and washer welded in so as can tune.

Heads -------$600 plus shipping
cyl&Pistons---$200 Plus shipping
Propipe-------$125 plus shipping
Here is info from S&S cat. on heads

.One of the most important things that needs to be done to get more horsepower out of any engine is to get more air into it. 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.

Combustion chamber sizes of 79cc and 89cc are available. Heads with the 79cc chamber are designed for 88" and 95" engines using the stock H-D® pistons or the optional S&S 3-7/8" bore "pop-up dome" pistons, and for 100" S&S Super Sidewinder™ engines. The 89cc heads are intended for larger displacement S&S 4" bore Super Sidewinder™ engines, and do not work with stock pistons due to inadequate valve-to-piston clearance. All current production S&S Super Stock™ Twin Cam® style cylinder heads with 89cc chambers are machined to accept the S&S compression releases. This allows riders to use either the manual or electric S&S compression releases. Threaded plugs are provided to seal the machined holes in the heads if compression releases are not used.

S&S Super Stock™ cylinder heads are available in natural aluminum finish or black powdercoat finish. They readily bolt on and accept all stock components except the intake manifold. They are also compatible with most parts designed for stock H-D® heads including head gaskets, exhaust systems, and rocker arms.

Notes:
• All early S&S Twin Cam® style cylinder heads were compatible with stock rocker covers, but current Twin Cam®-style heads must be used with S&S Twin Cam®-style die-cast rocker covers. 79cc heads are still compatible with factory rocker boxes.
• If 89cc heads are used with stock H-D® pistons, valve reliefs in the pistons must be machined. Both 89cc and 79cc heads may be decked as much as .060" to increase compression. If heads are decked, valve to piston clearance must be checked. If stock H-D® pistons are used, valve pockets must be remachined.
• Valve spring force of S&S Super Stock™ Twin Cam® style cylinder heads is fairly moderate to allow the use of cam shafts designed for the stock style chain cam drive system. However, for maximum reliability and performance we recommend the S&S gear drive cams.
• Due to the larger intake valves and chamber, 89cc heads have improved flow. This makes them better suited for large displacement engines.
• S&S cylinder heads for Twin Cam®-style engines with 79cc and 89cc chambers use different valve sizes so it is important to order the correct replacement valves. Valves have part numbers etched below the keeper grooves for easy identification. Twin Cam® and Evolution®-style engines use the same rocker arms and valve springs.
• S&S compression releases are highly recommended to aid starting in big inch, high compression engines.
