NOTE: Other S&S products such as stroker kits, stock replacement and Sidewinder® big bore cylinders, Super series carburetors, chrome moly steel pushrods,
and solid lifter conversion kits can enhance the performance of shovelhead engines. Many such parts are available in a Hot Set Up Kit® at cost less than that
of individual items purchased separately.
KIT CONTENTS:
•
One set of cylinder head assemblies with valves, valve springs, valve guide seals and keepers installed. Heads are also available bare.
• Rocker housing gaskets, head gaskets, and exhaust flange gaskets. Hardware for rocker housings, top engine mount, carb support bracket, and
exhaust pipes is also provided.
INSTALLATION STEPS
1. Strip Motorcycle
2. Clean and Inspect Parts
3. Install Rocker Housings
4. Install Cylinder Heads
5. Replace Parts Removed for Installation
Installation of S&S Super Stock® Cylinder Heads for shovelhead models is essentially the same as stock. No special tools other than those used in
normal top end repair are required.
In the instructions that follow, references are made to procedures described in an authorized Harley-Davidson® Service Manual. For this reason, a
Service Manual for the appropriate year group and model should be available during installation. Read all instructions thoroughly before beginning,
and proceed only after they are completely understood.
1. Strip motorcycle
Remove battery, gas tanks, exhaust pipes, top engine mount, carburetor, intake manifold, pushrod assemblies, and all other parts required to
remove cylinder heads. Remove cylinder heads, referring to Harley-Davidson® Service Manual as necessary.
Sparks from motorcycle electrical system can ignite gasoline fumes. To prevent sparks as well as prevent electric starter from becoming
engaged inadvertently and causing personal injury, disconnect battery and remove from motorcycle before proceeding.
Gasoline is toxic when inhaled, extremely flammable, and explosive under certain conditions. Do not smoke around gasoline, and
perform installation in a well ventilated area away from sparks and open flame.
2. Inspect and clean parts
A. Remove rocker housing assemblies from cylinder head. Disassemble and inspect as explained in Harley-Davidson® Service Manual.
NOTES:
•
Pay particular attention to rocker shaft fit in bushings and condition of rocker arm surface that contacts valve tip. Install new shafts or bushings and
reface or replace rockers as needed.
•
Unless top end has been rebuilt recently and is known to be in good condition, S&S recommends cleaning and inspecting pistons and cylinders to
determine if wear is within acceptable limits. Regardless of finding, light cylinder hone and new piston rings will prove beneficial for most engines having
more than a few thousand miles of service.
B. Clean housings and other parts thoroughly with solvent, and blow compressed air through oil passages.
NOTES:
•
Leaking oil line fittings should be removed and reinstalled with PTFE plumber's tape or other thread sealant. Reassemble rocker assemblies and
housings according to Harley-Davidson® Service Manual, using new rocker shaft o-rings. Lubricate o-rings with assembly lube or light grease to prevent
damage during installation.
•
Clean oil feed lines in solvent and blow through with compressed air to remove possible debris and solvent residue. Thoroughly clean head bolt threads
with solvent and wire brush. Replace bolts that are stretched or otherwise damaged and test fit by threading into heads before installation.
