BR SERIES LS COMPATIBLE/12 DEGREE CYLINDER HEADS
BRODIX delivers the industry's most durable
replacement for the LS style cylinder heads
with the introduction of the BR series. The
BR 7 is an out-of-the-box version that comes
standard with 71 cc combustion chambers,
bowls blended, and intake ports matched.
The STS BR 7 is a 100% CNC ported version
that flows over 375 cfm. The BR 7 and the
STS BR 7 both utilize a 12° valve angle and
2.204 / 1.614 valve combination. The
STS BR 7 273 flows over 415 cfm with a
71 cc combustion chamber and 2.250 / 1.614
valves. The BR 7 series heads accept all
standard LS components and share all of the
legendary BRODIX features including: easily
repairable A-356 virgin aluminum alloy and
the strongest deck surface in the business.
