Brodix BR3, BR9, BRA (LS3,LSA,LS9)
With the combined feature of having a rigid Brodix A-356 aluminum casting with LMEs own porting, the BR3 cylinder head is an excellent choice when looking to improve beyond the factory GM LS3, LSA, or LS9 head. Standard attributes include precision CHE manganese guides with hollow stem intake and stainless exhaust valves. Steadfastness has never been so feasible for your LS3 headed power plant.
## By specifying your cam lift LME will assemble your cylinder heads with the proper spring installed height. This will result in optimal spring pressures and coil bind distance for maximum performance. Please include rocker ratio to ensure acuracy. (example: .650" lift with 1.8 ratio intake and exhaust)
All Cylinder Heads Are Priced As ASSEMBLED Pairs
