The intake face, exhaust face and exhaust ports have been redesigned, valve guide bosses are profiled and casting walls are cleaner and more consistent, resulting in greater control over flow, heat and combustion. Multiple intake sizes are available to suit engines from mild street to big-inch full competition.
