Trickflow PowerPort CNC Ported 225cc Bare Cylinder Head Casting, Ford 351C/M/400 Clevor, 72cc Chambers

Trick Flow PowerPort® Cleveland 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. The heads feature fully CNC Competition Ported runners with a premium high resolution surface finish for maximum, all-out performance.

PowerPort® Cleveland 225 heads fit Ford 351C, 351M, and 400 engines out of the box. With minor machining, the heads also fit Ford 302/351W blocks to create a “replica” Boss 302 or a 351 “Clevor” engine. The heads are available fully assembled or as bare castings. Sold individually.
