This is a matched pair of 1970 LS6 ZL1 L88 427 3946074 aluminum rectangular port heads. These are correct for COPO Camaro Corvette ZL1 Aluminum 427 375 HP 396 L89 Nova Camaro Chevelle LS6 454. These heads were built by Valley Head Service of Southern California. They have a few repairs that were done by them, no stud bosses have been broke or repaired. These are ready for a mild rebuild and installation. They come with springs and retainers. Dated May and June of 1970.

The majority of items I sell are pre-owned, used items unless otherwise noted. Please keep in mind these are generally collector car parts in excess of 30 years old, they may not be perfect. If you have specific questions, please ask them before you bid. Returns are accepted if the item was misrepresented. I am always willing to combine shipping on multiple items as long as they can be safely packed together. Large, heavy or hard to pack items may take up to a week to ship.

Thanks for looking and Happy Motoring!
