Trick Flow engineers altered the valve angles from 15° to 13.5° to decrease valve shrouding, increase mid-lift airflow, and improve rocker arm-to-valve cover clearance. Material was added at the rocker arm mounting points to increase high-rpm valvetrain stability. The spark plugs were relocated in the CNC-profiled combustion chambers to enhance mid-lift airflow and increase the rigidity of the casting for extreme horsepower applications. Top-of-the-line CNC Competition Ported runners have a premium high resolution surface finish for maximum flow and performance.\u003c\/p\u003e","brand":"Trick Flow Specialties (TFS)","offers":[{"title":"Default Title","offer_id":52041705554214,"sku":"TFS-3051B001-C00","price":949.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/1666\/1542\/files\/tfs_205cc.jpg?v=1770813154","url":"https:\/\/billysspeedshop.com\/products\/trick-flow-gen-x-205cc-4-8-5-3-bare-casting-sold-individually-tfs-3051b001-c00","provider":"Billys Speed Shop","version":"1.0","type":"link"}
