To improve the factory design, Trick Flow added more material to the A356-T61 aluminum castings for increased rigidity and strength. Then Trick Flow improved the valvetrain system by integrating modular one-piece, 2024-T4 billet aluminum rocker arm mounts that are removable for high-end shaft rocker setups. Trick Flow’s high flow, high velocity CNC Competition Ported runners with the premium high resolution surface finish provide all-out air flow and performance throughout the entire powerband. Other major improvements include the available 6-bolt per cylinder clamping for GMPP LSX and other aftermarket blocks, clearance for 3\/8\" pushrods, through-deck coolant holes to fit all GM LS gasket and block combinations, Trick-Alloy powdered-metal valve guides, and solid stem valves.\u003c\/p\u003e","brand":"Brian Tooley Racing","offers":[{"title":"Default Title","offer_id":52041705488678,"sku":"TRICK FLOW CNC PORTED 6 BOLT 260CC LS7 CYLINDER HEADS","price":3279.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/1666\/1542\/files\/260_ls7.jpg?v=1770813230","url":"https:\/\/billysspeedshop.com\/products\/trick-flow-cnc-ported-6-bolt-260cc-ls7-cylinder-heads","provider":"Billys Speed Shop","version":"1.0","type":"link"}
