S&S P-Series Cylinder Heads

£1,259.00

Description

These cylinder heads are used by S&S to build their P-series engines, but may also be installed on most Shovelhead engines to give a nostalgic look and a performance boost over stock. The stock Shovelhead bolt pattern and the availability of heads with stock bore and S&S 3 5/8" bore fire-ring machining makes them compatible with most Shovelhead cylinders. The intake ports accept o-ring style manifolds for Shovelheads and the exhaust ports will bolt up to any exhaust system for a Shovelhead engine. Although the top surface of the heads accepts a stock Panhead rocker cover, a special S&S rocker cradle is required to support the rocker arms. These cradles are not suitable as a stock replacement, but designed specifically for these cylinder heads and to be used with S&S roller rocker arms for Shovel engines and top-end oiling through the pushrods. Most adjustable pushrods for Shovelhead models are machined for this. Several of the modern features have been incorporated and include S&S .590" lift valve springs, cooling channel between combustion chamber and rocker arms and late style valve chamber to eliminate oil pooling. Cylinder heads are sold in pairs of front and rear and come complete with valves and valve springs installed. Roller rocker arms, rocker cradles, rocker cradle dowel pins, rocker arm shafts and rocker shaft clips must be ordered separately. Cylinder heads come in natural aluminum finish.

Note: These are not stock replacement cylinder heads for Panhead engines, They will not fit on stock or aftermarket Panhead cylinders.

These parts are not held in stock and are ordered in at point of order, you will be notified of delivery date.
