Product Description

The new FLOTEK LS3 head features as-cast high flow intake runners that flow significantly better than the stock LS3 heads. In back to back testing at .650 lift, the FLOTEK LS3 flow tested 44 CFM better than the stock LS3 heads. The FLOTEK LS3 has a 276cc intake runner, 92cc exhaust runner, and 68cc combustion chamber. The ports are in the stock location so no special valve train parts or rocker arms are required. The heads are a 15 degree, which is the same as the stock cylinder heads so no special pistons are required. The FLOTEK LS3 will work on any LS block that has a 4.000" bore or bigger. These heads combine high performance and high quality at a value price.
