If you have an LS engine and want Gen-V LT-style heads or vice versa, this tool allows that. If you have a Gen-V LT vehicle but want all the tunability and performance of an LS top end, this tool will allow you to run LS-style heads on your LT short block. \u003c\/span\u003e\u003c\/p\u003e \u003cp dir=\"ltr\"\u003e\u003cspan style=\"font-size: medium;\"\u003eThis tool is custom-made by our specifications and manufactured by an \u003cstrong\u003eAmerican-made\u003c\/strong\u003e tool company we trust.
