S&S Cycle Assembled Cylinder Heads

• Fully assembled S&S Cycle heads for stock and 3-5/8″ bore Evolution engines were originally designed for engines using stock crankcases

• 3-1/2″ bore heads can be used with stock cylinders

• Although these heads are machined with the stock Evolution cylinder pattern and may be used on stock crankcases, special pistons are required with a “pop up” dome shape that matches the contour of the S&S Cycle combustion chamber for maximum performance

• Natural finish

Made In The USA This product was proudly made in the USA
