Introducing our Brawler Series CNC LS6 Heads! Our goal with the Brawler series cylinder heads are to provide a standardized on the shelf, in-stock cylinder head that can ship out very quickly and to provide our customers with an incredible bargain!

If you are looking for a great replacement/upgraded LS1/LS6-style Cathedral Port cylinder head, look no further than these fully CNC ported Brawler cylinder heads!
