FULLY CNC PORTED HIGH-PERFORMANCE DESIGNS For the ultimate in performance, our E-CNC cylinder heads are the answer. These cylinder heads are fully CNC ported for maximum horsepower and torque, making them ideal for high-performance street and light duty racing applications. They also feature high-quality lightweight valve springs and heavy duty hardware for maximum lift and maintain the stock exhaust port location. E-CNC cylinder heads are available for small-block Chevy, LS-series Chevy, big-block Chevy and small-block Ford.

IMPORTANT NOTES FOR LS3 CYLINDER HEADS
  • E-CNC LS3 cylinder heads are a great general purpose high performance cylinder head for any street- strip LS engine.
  • These cylinder heads have a high velocity port compared to stock LS3 cylinder heads, making them an ideal upgrade for any cathedral port or 3.89" bore LS application.
  • They feature an improved design and casting that gives cylinder head porters more material to work with compared to stock heads.
  • Like all of our other E-CNC cylinder heads, these feature fully CNC'd intake ports, combustion chambers and exhaust ports for improved performance.
  • Compatible with stock style rocker arms.
  • Features an exhaust port that has been raised 0.125" as well as raised spring pockets that have been machined 0.200" for use with longer valves.
  • Valve angle has been rolled to 13.25° and the spark plug position has been revised for improved combustion and efficiency over a stock head.
