Borowski Race Engines has used our tuned-up version of the Brodix STS BR7 273 CNC ported head for many of our Whipple supercharged LS7s including the monster in the dyno video. When you are airing out an LS7 with a 4.5L Whipple and nitrous, you need to have heads that first and foremost, will stay together. To make big power, they also need to flow. These heads accomplish both tasks.

We can supply the full range of Brodix BR7 heads in a range of configurations: bare, assembled by Brodix or customized by us. Most of our LS7 builds, including the one in the video, are intended for street. Our CNC valve job, among other things, changes the intake valve angle from 50 degrees to 45 degrees to improve longevity. The build in the video used Manley Severe Duty ProFlo valves. Want titanium valves? Not a problem.

Here's what Brodix says about their complete line:
"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 7 285 BS 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 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."

After reading that, you probably still have questions about which set-up is best for you. We will be happy to take your call at 815-725-2727. You will find it's a different experience talking with real engine builders as compared to some online virtual retailer.
