BRODIX delivers the industry's most durable replacement for the LS style cylinder heads with the introduction of the BR series. The STS BR 7 273 flows over 415 cfm with a 72 cc combustion chamber and 2.250 / 1.614 valves. The BR 7 heads accept all standard LS components and share all of the legendary BRODIX features including: easily repairable A-356 virgin aluminium 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 special rockers.
