Hello,
OEM used pair of C5OE hi-po heads. Standard size Fomoco valves. OEM springs and retainers. Unmolested set that weren't rusty and has never been resurfaced or altered in any way. When I got them they were said to have been pulled from a running engine and they did not smoke. I sent these to a reputable shop in Valencia, CA and had them cleaned, inspected, and confirmed that there are no cracks. These would be good candidates for somebody who is looking for a fresh start with a set of heads to rebuild.
