Return PolicyEconomical out-of-the-box horsepower is what comes to mind with this new series of Dragon Slayer heads from BRODIX. The new Dragon Slayer 225 comes standard with CNC ported 68 cc combustion chambers allowing this port to flow over 300 cfm @ .600 cam lift. The best thing about this head is that all standard components such as rockers, lifters, and intake manifold may be used.
