Those have been for sale for a while, 6 months to a year ago. There is a post in the leads from back then. Neat just $$$$ Regards,
way optimistic on the price..i get it, unuasual or rare..but..it puts it out of the price for an enthusiast i dont know what they are worth, but 4 or 500 each seems realistic to me..i dunno..
I`m gonna` venture a guess these heads came from a local machine shop that bought out what stock was left of Gray Marine. Buick manufactured engines for Gray Marine including 401 v8`s. At one point they had NOS crankshafts, heads, complete marine engine app takeouts that I heard were almost not rebuidable when opened up. They still have a ton of stuff but pretty sure the stuff that will cross into automotive is all gone. If these werent so pricey they would have landed in Tommy`s Toyhouse a long time ago... Tom
