Edelbrock E-street cylinder heads offer American made quality and affordable performance. 

They are recommended for entry-level street performance applications operating in the idle-to-5500 rpm range. 

These heads feature A356 aluminum 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. 

Every E-Street is assembled with manganese bronze valve guides, powder metal interlocking valve seats, stainless steel one-piece valves with hardened tips, 1.25" diameter valve springs, 3/8" screw-in studs and guide plates.  Additional qualities include hardened spring cups for long-term wear protection and Heli-coil threaded inserts in the rocker stud bosses for increased strength.  These are the details that most low-cost competitors leave out of their heads. 

All E-Street cylinder heads are sold in pairs and are currently available for SB Chev, BB Chev and SB Ford.
