Default Casting Number Head Question

Having an E-Bay dispute with a seller advertising Buick Grand National Heads with casting number 25527515. He is stating that these heads are 85-88 3.8 Buick Grand National Heads. He is proclaiming that AERA is listing this casting number as 85-88 Turbo Heads. Please send any information on this subject to help with this dispute. If I am correct there is only 1 set of heads that Grand Nationals use and they are turbo heads.

Question Re: Casting Number Head Question

http://www.gnttype.org/techarea/pict...headguide.html goes specifically to the head section. Also see http://www.gnttype.org/general/v6hist.html 25518445 is the number for the 83-87 head for the TRs. Note that turbo heads are the same as non-turbo. Just that the turbo have bridged water passages. Non-turbo cars may as well, but I've heard that not all may. See the pics.

The number you gave is a FWD '87 crank part number according to that second chart. Definitely not a head.
