Some of the 907 emission heads had eight air injection ports on the exhaust side where the air injection rail was attached. The GT 907 engine may have these ports.  I have seen two 907 emission heads with air injection ports.  One still had the original air rail attached and the other had plugs in the air injections ports.  If the GT 907 engine you are looking at still has the air rail you may need to find plugs for the air injection ports.
