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 225 cylinder heads. The heads feature intake and exhaust runners based on the OE Ford 2V design. The exhaust runners are raised 0.100 in. 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 225 heads feature fully CNC-ported 225cc intake and 115cc exhaust runners, 60cc combustion chambers, and your choice of 1.460 in. or 1.530 in. 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 in.\/1.600 in. valves, ductile iron valve seats, chromoly retainers, machined valve locks, Viton® fluoroelastomer valve seals, 7\/16 in. ARP rocker arm studs, and your choice of valve spring packages. Bare cylinder head castings are also available. \u003cstrong\u003eSpecs:\u003c\/strong\u003eApplication: For Ford Small Block 351C, 351M\/400 Cylinder Head Style:Assembled\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cdiv\u003eCylinder Head Material:Aluminum\u003c\/div\u003e  \u003cdiv\u003eCylinder Head Finish:Natural\u003c\/div\u003e  \u003cdiv\u003eCombustion Chamber Volume (cc):60\u003c\/div\u003e  \u003cdiv\u003eCNC-Machined Combustion Chamber:Yes\u003c\/div\u003e  \u003cdiv\u003eIntake Runner Volume (cc):225cc\u003c\/div\u003e  \u003cdiv\u003eExhaust Runner Volume (cc):115cc\u003c\/div\u003e  \u003cdiv\u003eCNC-Machined Intake Runner:Yes\u003c\/div\u003e  \u003cdiv\u003eCNC-Machined Exhaust Runner:Yes\u003c\/div\u003e  \u003cdiv\u003eIntake Port Location:Standard\u003c\/div\u003e  \u003cdiv\u003eExhaust Port Location:Raised\u003c\/div\u003e  \u003cdiv\u003eIntake Valves Included:Yes\u003c\/div\u003e  \u003cdiv\u003eIntake Valve Diameter (in):2.080 in.\u003c\/div\u003e  \u003cdiv\u003eExhaust Valves Included:Yes\u003c\/div\u003e  \u003cdiv\u003eExhaust Valve Diameter (in):1.600 in.\u003c\/div\u003e  \u003cdiv\u003eValve Springs Included:Yes\u003c\/div\u003e  \u003cdiv\u003eMaximum Valve Lift (in):0.680 in.\u003c\/div\u003e  \u003cdiv\u003eOutside Diameter of Outer Spring (in):1.560 in.\u003c\/div\u003e  \u003cdiv\u003eDamper Spring Included:Yes\u003c\/div\u003e  \u003cdiv\u003eNumber of Springs Per Valve:Dual\u003c\/div\u003e  \u003cdiv\u003eRetainers Included:Yes\u003c\/div\u003e  \u003cdiv\u003eRetainer Material:Titanium\u003c\/div\u003e  \u003cdiv\u003eLocks Included:Yes\u003c\/div\u003e  \u003cdiv\u003eLock Style:10 degree\u003c\/div\u003e  \u003cdiv\u003eValve Stem Seals Included:Yes\u003c\/div\u003e  \u003cdiv\u003eRocker Arm Studs Included:Yes\u003c\/div\u003e  \u003cdiv\u003eRocker Arm Nut Thread Size:7\/16-20 in.\u003c\/div\u003e  \u003cdiv\u003eRocker Arms Included:No\u003c\/div\u003e  \u003cdiv\u003eRocker Arm Nuts Included:No\u003c\/div\u003e  \u003cdiv\u003eGuideplates Included:Yes\u003c\/div\u003e  \u003cdiv\u003eGuideplate Pushrod Size:5\/16 in.\u003c\/div\u003e  \u003cdiv\u003eValve Cover Mounting Style:Perimeter bolt\u003c\/div\u003e  \u003cdiv\u003eAccessory Bolt Holes Drilled:Yes\u003c\/div\u003e  \u003cdiv\u003eValve Guides Included:Yes\u003c\/div\u003e  \u003cdiv\u003eValve Guide Material:Bronze\u003c\/div\u003e  \u003cdiv\u003eValve Seats Machined:Yes\u003c\/div\u003e  \u003cdiv\u003eValve Seat Machine Style:3-angle\u003c\/div\u003e  \u003cdiv\u003eValve Seat Material:Ductile iron\u003c\/div\u003e  \u003cdiv\u003eSteam Holes Drilled:No\u003c\/div\u003e  \u003cdiv\u003eOiling Style:Through pushrod\u003c\/div\u003e  \u003cdiv\u003eMachined for O-Ring:No\u003c\/div\u003e  \u003cdiv\u003eHeat Crossover:No\u003c\/div\u003e  \u003cdiv\u003eQuantity:Sold as a pair.\u003c\/div\u003e  \u003cdiv\u003e \u003c\/div\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cbr\u003e .\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e \u003cbr\u003e\u003cbr\u003e","brand":"Trick Flow Specialties","offers":[{"title":"Default Title","offer_id":44676301848887,"sku":"TFS-5161T005-C01","price":4177.55,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/214384.jpg?v=1780423127","url":"https:\/\/enginemaster.com.au\/products\/trick-flow-specialties-tfs-5161t005-c01-trick-flow-powerport-225cc-cyl-heads-alloy-complete-ford-351c","provider":"Engine Master","version":"1.0","type":"link"}
