| 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.

| 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.

| 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. |

| 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! |
