WARNING: For Proposition 65 information, see pg. 2 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 fl ow, 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 fi nish—perfect for mild-to- moderate performance applications. The PowerPort 225 heads feature fully CNC Competition Ported runners with a premium high resolution surface fi nish for maximum, all-out performance. PowerPort Cleveland series heads fi t Ford 351C, 351M, and 400 engines out of the box. With minor machining, the heads also fi t Ford 302/351W blocks to create a “replica” Boss 302 or a 351 “Clevor” engine. Cylinder heads are available fully assembled or as bare castings.

TFS-5161T003-C01 Dyno Results PowerPort Cleveland 225 “Thanks to Trick Flow PowerPort Cleveland 225 cylinder heads and Track Heat® 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. It’s been on the Hot Rod Power Tour, the Woodward Dream Cruise every year, and all over the United States without worry.” Michael Callahan 1969 Mercury Cyclone Spoiler II 408 c.i.d.
