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

440 EZ

Long valve stem design
270cc intake port volume
Stock exhaust port location
Stock intake opening
Stock pushrod location
Stock rocker arms
Stock rocker shaft oiling
2.19 x 1.81 valves
75cc closed or 80 cc open cbr

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.

440 EZ-1

Long valve stem design
275cc intake port volume Stock exhaust port location
Stock rocker arms
Stock pushrod location
Stock rocker shaft oiling
2.19 x 1.81 valves
75cc closed or 80cc open cbr
CNC Max intake and bowl port

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.

440 EZ-295 CNC "Little Easy"

Long valve stem design
295cc intake port volume
Stock exhaust port location
Full CNC port 295 cc intake
Stock pushrod location
440-1 shaft oiling
Max Wedge intake opening
78cc closed or 82cc open cbr
2.19 x 1.81 valve 355 CFM

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.

440 EZ-325 CNC "Big Easy"

Long valve stem design
325cc intake port volume
Stock exhaust port location
Full CNC port 325 cc intake
Stock pushrod location
Offset intake rockers needed
440-1 shaft oiling
78cc closed or 82 cc open cbr
2.19 x 1.81 valve 370 CFM

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.

426-1 Legend aluminum heads

The legend lives on! Our biggest challenge to date was to design new life into an almost forgotten normally aspirated engine. Integral cast iron rocker stands, moveable rocker shafts, exhaust valve relocation, taller valve cover rail, .350” longer intake valve and raised intake and exhaust ports with superior airflow breathes new life in the redesigned Legend head from Indy Cylinder Head. Long valve design- feel the power!

Moved exhaust angle and raised port
Integral rocker stands
170cc chamber volume
251cc intake port volume

426-1RA Legend aluminum heads

The 426-1RA legend head is a great choice for blown street machines or serious bracket racers that have tremendous horsepower needs. This head is best suited for a 500” cubic inch or larger bracket engine. Indy has incorporated a raised exhaust port to balance out intake to exhaust air flow percentages. This head also features an exhaust valve that has been relocated 2 degrees toward the cylinder wall in order to gain valve to valve clearance. This makes sinking valve jobs or cutting valves for clearance a thing of the past. Internal rocker stands along with Indy 426-7 rocker rollers make this a superior combination. Long valve design- feel the power!

Moved exhaust angle and raised port
Integral rocker stands
170cc chamber volume
251cc intake port volume

426-1RA6 Legend aluminum heads

The 426-1RA6 is a serious legend head for bigger cubic inch engines. Take for example a 605” cid or 636” cid which need every bit of the 500 cfm airflow and 325 cc intake port volume to produce loads of horsepower. This head has all the good features: +.350” longet intake valve, raised intake port, integral rocker stands, exhaust valve rotated 2 degrees toward the cylinder wall and raised exhaust ports. Build a 605 cid engine with our 426-4 4500 big volume intake and watch out...you’ll have a 1,000 HP single four barrel monster on your hands.

Moved exhaust angle and raised exhaust ports
integral rocker stands
2.100” wide x 2.200” tall 10 bolt intake port
160cc chamber volume
Flat face valves
325cc intake port volume

Billet Legend aluminum head

The Billet Legend head is a product of countless hours of research and development both in house and at the track. This head features one of the largest volume intake ports for a Hemi in the industry (330cc!). This, along with longer intake valves and raised intake runners provides great airflow characteristics. The Billet Legend is a great choice for Pro Mod, tractor pulling, monster trucks, or any blown acohol application. Where else in the country can you purchase heads for your blown alcohol race car and on the same order buy heads for the truck you pull it to the track with? Nowhere but Indy!

Moved exhaust angle and raised exhaust port
Integral rocker studs
2.300” wide x 2.350” tall 10 bolt big intake port
160cc chamber volume checked with flat face valves
325cc intake port volume for large C.I.D. engines

The New Indy Predator Head

The new Indy Predator head is just what you need to give the Big Chief or Big Duke head Chevrolets a run for their money. The canted predator design (10 degree intake, 5 degree exhaust ) is by far the best flowing, most efficient head availavle for the 4.800 bore spacing Chrysler, Hemi or Wedge 2.450 x 1.840 head diameter valves.

Small block aluminum head kits

When we decided to make small block heads we used our proven format: light weight castings, long valves and the proper port volume. These heads work on a stock block and take advantage of the 18 bolt head bolt pattern found on the “R” series blocks from Mopar Performance. These heads will transform your small block into a serious street machine or a very reliable, very powerful bracket engine. Since 400”+ cid small blocks are common, our 360-1 rectangular port head was created to fill the bill perfectly.
