GM LT1 Direct Port Injection Heads

GM's newest cylinder head just got even better!  The New Direct Port Injection LT1 heads found on the 2014 C7 Corvette and full size trucks is now exclusively available through Xtreme CFM, done up the way we know best, to provide you with the most power producing head out there!


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.
