If you’re looking to crank up the performance of your LT engine, these Precision Race Components LT1 CNC 312cc ported cylinder heads are a solid choice. I’ve had my hands on a set, and let me tell you, they’re a game changer. Made right here in the USA—from casting to machining—you can feel the quality the moment you unbox them.

These heads have gone through some serious CNC and dyno testing, and the results speak for themselves. You’re looking at one of the most powerful LT-based cylinder heads on the market. With an intake volume of 312cc and a chamber size of 58cc, they’re designed to maximize airflow and boost your engine's output. The intake valve is a beefy 2.165 inches, while the exhaust valve measures 1.600 inches. That’s some serious breathing capacity!

  • The heads come fully assembled with a TSP .660 Spring Kit, which includes PAC valve springs and titanium retainers. Trust me, these components are built to handle some serious RPMs without flinching.
  • With a 6-bolt design and a thicker deck surface, they offer enhanced stability and durability, which is crucial for high-performance applications.
  • They feature CHE bronze guides, ensuring smooth operation and longevity.
  • These heads are versatile too; they’ll fit both standard GM 4-bolt and aftermarket LT 6-bolt style engine blocks, making them a great option for a variety of builds.

As for fitment, they’re compatible with a range of models, including:

  • Cadillac Escalade (2015-2019)
  • Chevrolet Camaro (2016-2021)
  • Chevrolet Corvette (2014-2019)
  • Chevrolet Silverado 1500 (2014-2022)
  • Chevrolet Suburban (2015-2022)
  • Chevrolet Tahoe (2015-2022)
  • GMC Sierra 1500 (2014-2022)
  • GMC Yukon (2015-2022)
  • And they’re even a universal retrofit for models from 1997 to 2018!

Just a heads up—these are meant for competition use only and aren’t legal for road use. So if you’re serious about track performance, these heads will definitely help you unleash the full potential of your engine. If you want to take your ride to the next level, these Precision Race Components cylinder heads are worth considering.
