PowerPort® Cleveland 195 and 225 Cylinder Heads for Ford 351C, 351M/400, and Clevor Trick Flow PowerPort Cleveland 195 and 225 cylinder heads feature runners based on the OE Ford 2V design. The exhaust runners are raised .100" from the stock location to improve the short turn radius and dramatically improve exhaust flow, and a revised oil return system improves oil drain back and includes provisions for mating with Ford 351W blocks. PowerPort 195 heads feature CNC Street Ported runners that are CNC-machined with a standard resolution surface finish—perfect for mild-to- moderate performance applications. The PowerPort 225 heads feature fully CNC Competition Ported runners with a premium high resolution surface finish for maximum, all-out performance.

Additional Airflow Results intake manifold, my engine makes the power needed to hit my goal of driving my street-driven 1969 Mercury Cyclone at 200 mph on the Bonneville Salt Flats. Being able to choose the combustion chamber size and valve spring package that worked with my 408 stroker’s cam made the heads a bolt-on-and-go deal. The engine makes great power and is stone-cold reliable. I drive my Cyclone regularly on the street.
