E-Street cylinder heads are an all new line of Edelbrock heads designed for entry-level street performance engines, ideal for operating in the idle to 5,500 rpm range. Manufactured in the USA, by Edelbrock, these heads feature A356 aluminium castings that are heat treated to T-6 spec for superior casting strength and quality. Their modern combustion chamber designs improve the combustion process and larger than stock intake and exhaust ports move more air through your engine. These features improve an engine's efficiency, resulting in more horsepower and torque and improved mileage potential. Bare heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves you will be using.
