Description

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 72 cc combustion chamber and 2.250 / 1.614 valves. The BP BR 7 BS 285 is 100% CNC ported and flows over 415 cfm. This version of the BR 7 has a 285 cc intake port and 72 cc combustion chambers. 2.250 / 1.580 valves are installed to accommodate the new, bigger high flow exhaust ports for turbo or blowers. The BP BR 7 BS 300 adds a newly designed 300 cc intake port that flows over 437 cfm. The BR 7 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. The STS BR 7 BS 273 has been added to the series for the racer who wants to use a 1.650 or smaller o.d. roller valve spring, but requires longer valves and special rockers.
