These are taken off of my ls3 belair, 6700 miles. Nothing wrong, I happened upon a set of lsa covers and Coils and a fast intake, so I made use of them. The covers are holley polished, I can strip them if you prefer the polished look. Gaskets are all fine, comes with hardware. For everything as shown, $550 shipped from Longview, TX. 228-243-3833, Let me know if you have any questions.
