Precision Race Components 237cc Cylinder Head
Alright, let’s talk about the Precision Race Components 237cc Cylinder Head. If you’re looking to get serious about your LS build, this head is where it’s at. We’re talking cathedral-port design that’s been flow-bench-tested to push out over 339 CFM. Whether you’re running a mild street cam or going all out with a race setup, this head can handle it.
This isn’t just any cylinder head; it’s designed for those who want to maximize their engine’s potential. You’ll need a minimum 4.00” bore to make the most of it, but trust me, if you’re going bigger than stock cubic inches, you’ll love what this head brings to the table.
What Makes It Stand Out?
- 237cc Fully CNC Ported Intake Runners: Precision is key, and these runners are built with that in mind.
- 84cc Fully CNC Ported Exhaust Runners: They flow like a dream, helping your engine breathe better.
- TSP .660 Spring Kit: Comes with PAC valve springs and titanium retainers. You’re going to want these for reliability at higher RPMs.
- 68cc CNC Machined Chambers: Perfect for getting the compression just right.
- CHE Bronze Guides: Built to last and handle the heat.
- 2.100” Hollow Stem Intake Valve / 1.600” Stainless Exhaust Valves: These valves are designed for performance without adding unnecessary weight.
- Factory Rocker Friendly: No need to swap out your rockers; this setup plays well with what you already have.
Fitment
This head fits a solid range of vehicles, so if you’ve got one of the following, you’re in luck:
- 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 GTO (2004-2006)
- Universal Retrofit (1997-2016)
Important Notes
- If you’re grabbing a Melling oil pump, remember to pair it with a single-roller timing set. Those double-roller setups just won’t fit.
- This setup is competition use only—don’t plan on taking it for a spin on the street.
So, if you’re ready to take your LS engine to the next level, the PRC 237cc heads are a solid choice. They’re built for performance, and they won’t let you down when it counts.
