Texas Speed & Performance Cathedral Port Heads & Cam Package for Cadillac, Chevrolet, GMC 1997-2017 - PRC-LS1HCPackage-CS

Rev Up Your Engine with PRC LS Cylinder Heads

If you're looking to give your LS engine a serious boost, you might want to check out these Precision Race Components (PRC) cylinder heads. They’re fully CNC ported and assembled, so you know you’re getting top-notch quality. You can choose between stock or stainless steel valves—2.02" intake and 1.575" exhaust—depending on what you’re after. Plus, there’s an optional TSP dual valve spring kit that comes with PAC valve springs and titanium retainers. Trust me, that’s a sweet setup for any serious build.

What’s in the Kit?

  • Complete CNC Machining: Your supplied cathedral-port heads will be milled to your specs, fully assembled, and pressure-tested. We’re not cutting corners here.
  • Choice of Camshaft: Pick a TSP camshaft that fits your performance goals.
  • TSP Hardened Pushrods: These are built to withstand the heat and pressure, giving you peace of mind on the track or street.

Fitment

These heads fit a range of vehicles, so you’re covered whether you’re working on a Cadillac CTS-V (2004-2007), a Chevrolet Silverado 1500 (1999-2013), or even a Pontiac GTO (2004-2006). Here’s a quick list for you:

  • Cadillac CTS-V 2004-2007
  • Cadillac Escalade 2005-2014
  • Chevrolet Camaro 1998-2015
  • Chevrolet Corvette 1997-2013
  • Chevrolet Silverado 1500 1999-2013
  • Chevrolet Suburban 2000-2014
  • Chevrolet Tahoe 2000-2014
  • Chevrolet Trailblazer 2006-2009
  • GMC Sierra 1500 1999-2013
  • GMC Yukon 1999-2014
  • Pontiac Firebird 1998-2002
  • Pontiac G8 2008-2009
  • Pontiac GTO 2004-2006
  • Universal Retrofit 1997-2016

Important Notes

  • The price listed is for customers sending in their own cathedral-port castings for the upgrade. You need to have a set ready to go; we don’t provide the castings.
  • If you’re thinking of pairing this with a Melling oil pump, remember to use a single-roller timing set. The Melling won’t fit with a double-roller setup.
  • Keep in mind, this is for competition use only—not street legal!

So, if you're ready to take your ride to the next level, these PRC LS cylinder heads might just be what you need. They’re built for performance and ready to handle whatever you throw at them. Let’s get building!
