{"product_id":"twisted-wedge-11r-190-assembled-cylinder-head","title":"Twisted Wedge 11R 190 Assembled Cylinder Head","description":"The Trick Flow® Twisted Wedge 11R® 190 Cylinder Heads represent an evolution of Trick Flow's performance-oriented cylinder head design for small block Ford engines. These assembled heads feature a restructured combustion chamber and revised valve angles (11° intake, 13° exhaust) to enhance airflow and overall performance potential. The high-velocity, race-inspired runners are optimized for popular bore and stroke combinations.\n\nConstructed from premium cast aluminum, these cylinder heads boast fully CNC-machined intake and exhaust runners, as well as combustion chambers, ensuring exceptional quality, durability, and dimensional accuracy. The 190cc intake runners and 66cc exhaust runners, paired with 56cc combustion chambers, contribute to improved performance. The heads come fully assembled with titanium retainers, dual valve springs, and exhaust valves.\n\nImportant installation notes indicate that these heads are machined for 1\/2” head bolts. Customers with blocks machined for 7\/16” head bolts will require the use of TFS-51400419 Head Bolt Bushings. The Twisted Wedge 11R heads are a direct replacement for previous Twisted Wedge heads and are compatible with all Twisted Wedge-specific pistons.","brand":"Trick Flow","offers":[{"title":"Default Title","offer_id":52689430511928,"sku":"TFS-5261T561-C02","price":1499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687738432.jpg?v=1784906546","url":"https:\/\/store.motormia.co\/products\/twisted-wedge-11r-190-assembled-cylinder-head","provider":"MOTORMIA","version":"1.0","type":"link"}
