| 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. |
