Speedmaster LS-series cylinder heads are rapidly expanding. The LS (Gen3/4) platform has many design benefits over the earlier SBC engine designs, most notably the cylinder heads. Although the GM heads are good pieces, We have developed a superior line of heads for modern performance enthusiasts.
This product would be best suited for engine builders and engine enthusiasts interested in upgrading their Chevrolet or GM performance vehicles, particularly models with the LS3 L92 or L76 engines, as it offers an assembled hydraulic roller system for improved cylinder head performance.
