I don't think the 074 opened chambered aluminum heads were ever used on 1969 L89 corvettes. I believe only later L88 and ZL1s. I believe all 1969 L89 corvettes (even late ones) got the 842 casting closed chambered aluminum heads. That paperwork, in my opinion, is questionable and the stamp pad needs cleaned and closer examination. I would suggest if anyone is serious about the car (pay the fee) and have the shipper/tank sticker numbers sent to the NCRS to validate it. Not going to validate any of the cars options but it will tell you if that is the correct tank/shipper order numbers for the car. In my opinion, the car has way too much going for it, if you know what I mean. The car is way over priced even if everything checked out
