Let me tell you about the Brawler Series CNC LS6 Heads—these aren't just any cylinder heads; they’re a solid upgrade for anyone looking to boost their LS1 or LS6 engine without breaking the bank. I’ve been around the block with a few different setups, and I can say these heads really pack a punch.
What I love about these Brawler heads is that they’re based on the factory GM LS6 design but with a twist. They’ve gone through a meticulous CNC porting process that really opens up airflow. You get the same CNC porting as the GM PRC ported LS6 heads, which means you’re getting some serious performance without the hefty price tag. Plus, they come fully assembled and tested, so you know you’re getting a reliable product right out of the box.
Now, let’s talk specs. These heads feature a 64cc combustion chamber, which is perfect for squeezing out that extra power. They’re equipped with TSP/PAC’s .660 spring kit, complete with titanium retainers, ensuring you’re set for high RPMs without any worries. The stainless steel valves—2.02” for intake and 1.57” for exhaust—are tough and durable, making them a great choice for anyone pushing their engine hard.
As for fitment, these heads are versatile. They’ll bolt right onto a range of models, including the Cadillac CTS-V from 2004-2005, Chevy Camaros from 1998-2002, Corvettes from 1997-2004, and even GMC Sierras up to 2007. Just keep in mind, these are meant for competition use only—not street legal, so save them for the track!
In short, if you’re looking to upgrade your LS engine with something that delivers real performance without a huge investment, these Brawler Series heads are worth considering. They’re built tough, tested, and ready to help you unleash your engine’s potential.
