{"product_id":"ls-engine-swap-headers","title":"LS Engine Swap Headers","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eLS Engine Swap Headers are purpose-built exhaust manifolds engineered for popular LS engine conversions across a range of classic Australian and 4WD platforms. Whether you're dropping an LS into a Holden Commodore, classic HQ-WB, Torana, Nissan Patrol or LandCruiser, these headers are precision-formed to clear the unique fitment challenges of each specific donor chassis — firewalls, steering components, chassis rails and transmission configurations included. Available for both manual and automatic transmission setups across most applications, and suits LS1 (Gen III), LS2 and LS3 (Gen IV) engines including 5.7, 6.0 and 6.2 litre variants.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul
