This set of heads and rocker arms came out of an estate in Southern California, they were re-built but never installed, they were put in storage many years ago, the springs on one head have some corrosion, as per the photos,Part number says they were built between 1959-66, but I don't know exactly what they came off of or what they will fit, it's up to the buyer to determine if this is the correct part they need, flat rate shipping is via UPS on a pallet and only applies to the lower 48 states, please email me for rates for anywhere else, international buyers must use the eBay global shipping program
