World Products

This is the cylinder head that highly respected drag racers like Scotty Richardson employ to win NHRA National event titles and literally hundreds of thousands of dollars in high stakes ET Bracket Races. Merlin III is a true high performance head, capable of supporting in excess of 800 HP out of the box. Take your pick between 310cc or 350cc intake runners. Assemblies include premium quality Manley RaceMaster or Severe Duty valves.

World Products offers heads in both aluminum and cast iron. For street engines, We recommend cast iron heads over aluminum. "Iron is better where weight or looks are not a factor because it retains heat better than aluminum and keeps the heat in the combustion chamber, which is where you want it. Cast iron heads will typically give you about 10 to 15 more horsepower than an identical set of aluminum heads on a street engine. As for the weight difference, a pair of cast iron small block Chevy heads weighs about 30 lbs. more than a set of aluminum heads. On a big block Chevy, the weight difference is about 85 lbs., which doesn't make much difference on a crew cab truck or RV, but does in a race car. For racing, you want the lighter aluminum heads."
