It is the culmination of over three decades of experience manufacturing cylinder heads and intake manifolds. It all began with the founding of CHI in the late 1990's, designing and manufacturing the first Hemi 6 alloy cylinder head and progressed to the world renowned CHI 3V Cleveland Cylinder heads and intake manifolds, as well as the Commander Windsor Intake Manifolds among others. Nowadays at CID we are focusing on our world renowned BE-LS and Small Block Ford intakes that have redefined the Horsepower potential one can expect from a cast single 4 intake. This manifold platform was the first and only cast single four intake to make over 1100HP on a NA Small Block and has been approaching 1200 HP NA on subsequent builds. We also have our Symmetrical Port Big Block Chevy Heads with matching intake manifolds as well as our record setting Gen V LT1 & LT4 cylinder heads, Inline LS Cylinder heads and our SB Ford SC2 Heads as well as the LS - CR cylinder heads. The SB Ford SC2 and the LS - CR are at the pinnacle of small block cylinder head design and have already become the casting choice of Top Tier Shops including BES Racing Engines, Ultra Pro Machine, MBE Cylinder Heads, Race Flow Development, TRE Race Engines, Slawko Cylinder Heads, Gwatney Performance Innovation, EIC Motorsports, Bennet Racing Engines, just to mention just a few. All castings are developed and manufactured in the USA, with extensive use of Computational Fluid Dynamics and Computer Aided Modeling. We are open and honest about our manufacturing choices so you won't find "sourced overseas" anywhere in our literature, or any Chinese castings in our inventory. Honesty, character and integrity matters to me, and you won't catch me in a lie. Over the years CID has grown into a niche manufacturer of elite Cylinder Head and Manifold designs with the help of some of the industries leading minds. I don't look to be price competitive but concentrate rather on product that offers a true performance advantage. I won't make a product because it's cool if it isn't the best version for making power. Whilst we are not the cheapest, it is the choice you will make for the very best in performance Cylinder Heads and Manifolds once you have completed your due diligence.
