CNC Ported Heads for Max Volumetric Efficiency

The AMS CNC Ported VR30 Heads unlock the full potential of your engine’s performance. Precision-engineered using advanced CNC technology, these cylinder heads offer superior airflow and combustion efficiency, delivering increased horsepower and torque. Ideal for high horsepower and high revving builds, our CNC ported heads provide consistent, high-quality results that will take your build to the next level. We’ve spent countless hours testing and refining this program and have optimized it to utilize the latest Ferrea and GSC valvetrain components crafted from exotic alloy materials made to with stand high boost and heat, as well as the forged billet GSC S2 cams designed for high RPMs and big power. With a 61 CFM intake and 30 CFM exhaust increase in airflow over stock, the AMS CNC head program is a proven solution to improve airflow in and out of the engine.

 

Our Race Winning Experience Creates Higher Standards

All of our built engines are individually handcrafted at AMS using the same care as the ones found in our world record setting race cars. When you choose an AMS engine you are investing in the knowledge gained from assembling thousands of race engines over the past 25 years. Just like in our 2800+ WHP ALPHA OMEGA Huracan, every motor is balanced, blueprinted and assembled to our precise specifications. Before assembly each block is checked for correct dimensions, cylinder bore, main alignment, block flatness, and more to ensure you get the best foundation for your new engine. Every engine we assemble has an archived spec sheet where tolerances, torque specs, and clearances are documented as part of our standard quality control process.

 

Product Notes

  • * Horsepower and torque numbers, and RPM limits are approximate and can vary significantly depending on numerous factors such as your turbocharger selection, intake and exhaust restriction/backpressure, and fuel octane and quality, among many others. The advertised numbers herein are based on optimal conditions and utilizing proper supporting modifications, but are generally attainable results by an average customer. Your results may vary.
  • In rare cases, our component selection may vary from advertised based on supply chain delays. All component substitutions will be communicated in advance by your AMS Sales Representative during the engine assembly process.
  • Assumes that a good condition core long block is sent in to build from. To avoid confusion and the possibility of missing parts we ask that all long blocks are shipped to us fully assembled from valve covers to oil pan, including timing covers. Components that are not in reusable condition will have replacements quoted during the engine assembly process.
