I have a set of '68 430 heads that have never been worked. They came out of a big car and are completely stock. I haven't Mag'd them so I can't tell you if they are good or not. But they are complete and show no visible flaws. They will definately need a rebuild before you use them. $20 for the set plus shipping, or best offer. Casting# 1382091 I'll post pics ASAP.
