For almost 30 years, the LS engine platform has been a cornerstone of the Chevrolet Performance lineup.


In addition to many crate engines,* the Bowtie LS offerings extend to a wide variety of parts, including LS9 CNC-ported cylinder heads.


These durable heads fit all LS engines with a 4.000” bore or larger and flow about 10 percent more than the production LS9 head.


In a new video, Chevrolet Performance Parts Product Manager James Bloss goes over the history and details of these powerful cylinder heads.
