These heads were carefully removed from a running and driving vehicle. The aluminum surfaces have some minor corrosion and average wear and marks from use, but are in good condition overall. There are no visible cracks or broken exhaust manifold bolts. There are a few scratches around the head gasket surface, but nothing that appears deep enough to cause issue. All threaded holes and mounting points are intact and undamaged. The rocker arms and stands are included, and do not have any axcess play in the trunions. These are considered by many to be the best factory cathedral port heads ever offered by GM. \u003cstrong\u003eAs with any engine parts we sell, we recommend having these checked by a machine shop prior to use, as they may need resurfacing or other repairs.\u003c\/strong\u003e The images are of the actual items you will receive. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 14pt; font-family: arial, helvetica, sans-serif\"\u003eFits the following models with 5.3L Flex Fuel L33 engine as a direct replacement: \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan style=\"color: #000000\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 14pt; font-family: arial, helvetica, sans-serif\"\u003e2005-2006 Chevrolet Silverado 1500 \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan style=\"color: #000000\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 14pt; font-family: arial, helvetica, sans-serif\"\u003e2007 Chevrolet Silverado 1500 Classic \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan style=\"color: #000000\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 14pt; font-family: arial, helvetica, sans-serif\"\u003e2005-2006 GMC Sierra 1500 \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 14pt; font-family: arial, helvetica, sans-serif\"\u003e2007 GMC Sierra 1500 Classic \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 14pt; font-family: arial, helvetica, sans-serif\"\u003eThese cylinders heads may also fit other GM Gen III and IV LS 4.8L, 5.3L, 5.7L and 6.0L engines. \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 14pt; font-family: arial, helvetica, sans-serif\"\u003eThese heads are directly interchangeable with 799 casting number heads. \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 18pt; font-family: arial, helvetica, sans-serif\"\u003eNo shipping outside the lower 48 states.
