I bought a 68 stang coupe with a 200 ci. just sold it yesterday to a fellow. he calls me today asking about these bolts on top that are only 1" long. My straight six knowledge is extremely limited, so i need your help. anyone know what they are?



Hopefully i can get him some answers!

Old air injection ports to the exhaust used in California spec Ford Sixes.


They have been blanked off, which is common

Thank you. It seems so simple after knowing what it is.
