Head casting No. 25518445

[slow 86 gn]

Are the BOP Buick Olds Pontiac heads off a 86 v-6 the same, has the same casting No. as the 86-87 GN 25518445. Can i use them on my GN? These heads are off a 86 front drive pontiac, looks kind of like the GN motor turned sideways, my head has a crack in the water jacket. Sucks to be me!!!

8445 head is a 8445 head

factory the turbo heads had different springs on them but the head itself is the same.
