sbc head info

I recently got some heads that were pulled off a 327 (I have no idea if they are original) and I've had trouble finding any info about them (their specs, what they came off of, etc...).

There casting numbers are: 576450

Anybody know anything about them?

Any way you could take a picture of one and post it here?

I can't find that casting # on any GM listing ...

I've already tried. Their site is down (at least for me).
