| Create some THUNDER at the drag strip with Pro Topline's Pro Lightning 23° cylinder heads for Big Block Chevy. Choose between Cast Iron or Aluminum - either way you still get the increased flow of multi-angle intake and radiused exhaust valve seats. In fact, Pro Topline says the 23° heads out flowed similar aluminum and cast iron heads on the market by 5% for a BIG improvement in low-end torque and top-end horsepower. Lightning heads also feature an improved water jacket design, which increases flow around the plugs for improved combustion, angles plug locations, and a three angle valve job. Best of all, they accept conventional piston and valve train components for easy bolt-on power. Available as bare castings or complete assemblies. | ||||||||||||||||||||||||||||||
