Cast with quality A-356 aluminum, .750" deck thickness, and a 6-bolt configuration, the Brodix BR7 castings are ideal choice for your boosted speedster. Cut with LMEs CNC porting and chamber work in house, the performance hike will take your ride to new heights. Standard adornments include CHE precision manganese bronze guides, titanium intake valves, and your pick of stainless or inconel exhaust valves.      

**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 accuracy. (example:  .650" lift with 1.8 ratio intake and exhaust)
