FLOTEK 276cc LS3 Cylinder Heads
FLOTEK 276cc LS3 cylinder heads feature as-cast high-flow intake runners that flow significantly better than the stock LS3 heads. The ports are in the stock location, so no special valvetrain parts or rocker arms are required. These heads are 15 degree, which is the same as the stock cylinder heads—no special pistons are required. They will work on any LS block that has a 4 in. bore or larger. FLOTEK 276cc LS3 cylinder heads combine high performance and high quality at a value price. Select from bare or assembled models.
