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 on the past. Integral rocker stands along with Indy 426-27 roller rockers make this a superior combination.
