I have a set of cylinder heads that are free to the first one to pick them up. I'm in south-central Connecticut.
The heads are 3917293 casting number and I believe about 75cc? I removed them from a one-owner 1967 Impala years ago and ran them on my 68 up until a few years ago. They were used on late 1967 Camaros.
The castings are fine but I would rebuild them.
Mike.
