is a 91 B2200 head interchangeable with 86 B2000 head? some guy at my job needs to know. also he said theres something that wont let him switch into reverse (its an automatic) but he said it's not the actual transmission but something else..
Both truck engines, the FE and the F2 use the same 8 valve head. They interchange. In your friends case, they are both B2200 - hydraulic lash adjusters, exactly the same.
