Trickflow PowerPort® Cleveland 190 and 225 Cylinder Heads for Ford 351C, 351M/400, and Clevor

With its free-breathing, canted valve cylinder head design, Ford’s 351 Cleveland was an engine that made big promises. The 2V version featured small-port cylinder heads optimized for low-speed torque. The 4V engines, however, had heads with huge intake ports that boosted top-end horsepower. What Ford did not do was make a version of the Cleveland that combined the torque of the 2V heads and the high-rpm rush of the 4V head design. But Trick Flow engineers picked up where the factory left off. They took the best qualities of the factory head designs, added a healthy dose of hot rodder ingenuity, and created the PowerPort Cleveland 190 and 225 cylinder heads. The heads feature intake and exhaust runners based on the OE Ford 2V design. The exhaust runners are raised .100" from the OE 2V location to improve the short turn radius, thus dramatically improving exhaust flow. The combustion chambers are fully CNC-profiled and bowl-blended to further maximize performance. The oil return system has been revised to improve oil drainback and includes provisions for mating with 351 Windsor blocks. The PowerPort Cleveland 190 heads feature Trick Flow’s Fast As Cast® intake/exhaust runner technology that provides near CNC-ported power and performance at a standard head price. These heads have 190cc intake runners, 112cc exhaust runners, and 62cc combustion chambers, plus your choice of 1.460" or 1.530" valve springs. The PowerPort Cleveland 225 heads feature fully CNC-ported 225cc intake and 115cc exhaust runners, 60cc combustion chambers, and your choice of 1.460", 1.550", or 1.560" valve springs. The PowerPort Cleveland heads fit 351C, 351M, and 400 engines out of the box. With minor machining, the heads can be used with 302 and 351W blocks to create a “replica” Boss 302 or a 351 “Clevor” engine. The PowerPort Cleveland heads come fully assembled with lightweight stainless steel 2.080"/1.600" valves, ductile iron valve seats, chromemoly retainers, machined valve locks, Viton® fluoroelastomer valve seals, 7/16" ARP rocker arm studs, and your choice of valve spring packages. Bare cylinder head castings are also available.
