The PANCHITO head is the newest addition to our high performance program! Perfect for those mild tuned engines! Super strong heads with all the features you need to build that perfect engine! The all new Panchito 044™ is dyno proven, horsepower making, ports cast right in. These port designs are race proven winners with years of use in engines around the globe. Countless hours were spent on our Superflow™ 600 flow bench designing the intake and exhaust ports. Our goals were to achieve the highest port velocity and air flow through a 40mm x 35.5mm size valve. The 40mm intake port has an extremely small port volume of 62cc and flows an incredible 162 CFM and over 300 ft. per second port velocity, right of the shelf! The 35.5mm exhaust port has a reduced bowl size and increased short turn radius creating phenomenal port velocity. This higher port velocity allows for improved low-end and mid-range performance without sacrificing top end power. CB Performance has also added extra material around the combustion chamber to give the Panchito 044™ more strength and support for larger bore cylinders. The all new high quench combustion chamber has a volume of 54cc, a perfect size for small displacement engines. The Panchito 044™ is designed to incorporate bore sizes from 85.5mm to 94mm. Available in all different bore sizes, they come with valves, springs and are ready to install.
