Head #'s

Big block heads got hardened exhaust seats starting in 1971. I understand why you are thinking this, but those are good heads. The problem is finding a buyer. I have several similar sets and can't find a buyer. I scrapped a VERY NICE pair of 1958 325 poly heads (Dodge) because I couldn't find a buyer...

Yeah, I've done the same thing. Couple of summers ago, I had to get up some money quick. I ended up scrapping several sets of 906s, 452s, 346s and one nice set of 915s. I even offered them on here for cheap and then for FREE, but no one would even pay to ship.
