{"product_id":"dhc-200-bare-cylinder-head","title":"DHC 200 Bare Cylinder Head","description":"The Trick Flow Specialties DHC™ 200 cylinder head is designed to build a high-performance Small Block Chevrolet engine with a classic aesthetic. Building upon the DHC™ 175 as-cast heads, the DHC™ 200 model undergoes a full CNC porting treatment to significantly enhance power output. The new 64cc CNC-profiled combustion chambers, paired with 2.055 in. intake valves and CNC Street Ported runners, are engineered to deliver substantial increases in high-RPM horsepower and torque.\n\nConstructed from A356-T61 aluminum, these cylinder heads are lightweight while maintaining durability. They feature bronze alloy valve guides and ductile iron valve seats, with proprietary valve profiles and multi-angle valve seat machining for optimized flow, especially at low lift. The design includes extra-thick decks and walls for added casting strength, providing confidence in demanding applications. To maintain a vintage appearance, the heads offer straight spark plug holes, and castings are available with or without accessory bolt holes, incorporating OE double hump head styling cues.\n\nThis specific model, TFS-3021B002-C00, is a bare cylinder head and does not include valves, valve springs, dampers, retainers, locks, stem seals, rocker arm studs, rocker arms, nuts, or guideplates. It is designed for use with a minimum bore diameter of 4.000 in. and features standard intake and exhaust port locations, a heart-style combustion chamber, and a rectangular intake port shape with a D-port exhaust shape. The head is sold individually.","brand":"Trick Flow","offers":[{"title":"Default Title","offer_id":52689428906296,"sku":"TFS-3021B002-C00","price":999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687736839.jpg?v=1784906528","url":"https:\/\/store.motormia.co\/products\/dhc-200-bare-cylinder-head","provider":"MOTORMIA","version":"1.0","type":"link"}
