440-EZ B/RB
Aluminum Cylinder Heads
475 to 750 HP Potential

The Indy Cylinder Head EZ heads are designed for A, B and E body cars. They have stock low exhaust port location and bolt patterns meaning that most standard exhaust headers will work. This means that if you want Indy power and want to use your existing stock exhaust headers, this is the head for you!

Like all Indy heads, EZ heads feature long valve design and a cast aluminum valley plate. More intake volume (280cc 440 EZ) equals more power. There are four different EZ heads to choose from

The as cast 440 EZ Indy head incorporates the original design raised intake runner and Indy aluminum valley plate. Stock 906 paper intake gaskets, stock exhaust gaskets and stock rocker arms are used. Angle spark plugs with standard low exhaust port and bolt pattern. This is a cure for common clearance problems. The 440 EZ-1 is the same cast head as the 440 EZ with the intake openings CNC machined to the Max Wedge size and CNC bowls. This allows all Indy manifolds to be used or all after market Max Wedge X-rams. Both EX and EZ-1 use standard Chrysler rocker shaft oiling. Standard low exhaust port. The Little Easy is the same cast aluminum head with full internal CNC porting. A high torque 295 cc Max intake runner and hi velocity low exhaust port. Must use 440-1 external shaft oiling. If you take off the cast iron 906 combo and add this you will gain 100 hp. The Big Easy is an expanded version of the Little Easy. The main difference is the volume of the intake runner. Offset intake rockers are required with external shaft oiling. The Big Easy is a must for racers who want a 540 cubic inches combo in their A body car with low exhaust ports.
