I have two sets of 8445 turbo heads. One set off my 86 T Type and one I purchased off of EBay. My T Type heads have a larger squared off exhaust valve guide boss. The EBay 8445 heads have identical valve guide bosses for both intake and exhaust. Also on my 86 head, there was a stem seal only on the intake valve. Any information as to the differences. Thanks.
