But they also offer fully CNC-machined heads with every intake port, exhaust runner, valve bowl, and combustion chamber shaped by their 5-axis, computer controlled machining centers to produce compound curves and complex shapes that no human could duplicate with a hand grinder. Available bare or fully assembled, long-wearing bronze valve guides, screw-in studs, multi-angle intake seats with hardened, radiused exhaust seats are standard on most heads. Assemblies typically include stainless steel valves, premium springs, locks, retainers, guide plates, and seals. Many Pro 1 heads include race-proven features such as improved spark plug location, extra-long intake valves, raised exhaust ports, and fast burn chambers. They are offered an extensive variety of valve angles, intake port volumes and shapes, exhaust port locations, valve sizes, and chamber volumes.
