The design of the cylinder head is key to the performance and efficiency, as the shape of the combustion chamber, inlet passages and ports determines a major portion of the volumetric efficiency and compression ratio of the engine. Butler LS takes cylinder heads seriously. We only partner with top head designers with extensive resources for R&D with proven race performance. Don't just buy a set of heads anywhere, come to the GM LS specialists that can help you pick the right head for your project.
