THE BADDEST CAST-ALUMINUM LS CYLINDER HEAD JUST GOT BADDER!
You asked. We delivered.
BTR's legendary canted-valve LS3 cylinder heads are now available with 58cc combustion chambers!
Same incredible airflow. Same proven performance. Now with even more squeeze!
Whether you're looking to wake up your LQ4 with a healthy 10.8:1 compression ratio, push your LS3 beyond 12:1, or squeeze every last bit of performance out of your small-bore LS combination, the new 58cc option gives you the compression to take things to the next level.
More compression. More power. Same BTR attitude.
