Send me an email to buickdav@yahoo.com . I have a set of 67's that I can have checked out and I "think" a set of 68's if I can find them. Later.............
I also have a set of 68 heads I won't be needing - casting numbers 1382091. They're not big port heads but they're in good shape. Can send post pics if you're interested. Not sure what to ask for them - make an offer? Shipping from Portland OR. Doug
