These heads are configured to your specific combination and available in many different runner volumes for the rectangle LS3  port. Only available exclusively through Xtreme CFM.


All xtreme cfm cylinder heads have gone through extensive research and development to provide you with the most powerful "out of the box" heads available on the market.


In development, our main objective was to provide the highest flow possible without ever sacrificing air speed in order to achieve it and staying within strict sizing constraints of each port. Not just emphasizing on flow alone, all aspects of the port were addressed with proper port shape, velocity, cross section and volume, with the end result of an extremely efficient head.
