'74 Duster Rebuild

Looks awesome! I see one thing you need to do before you put the motor back in, and you may already know about it. See the holes underneath each exhaust port? If whoever built the motor didn't tap those holes and screw a pipe plug into them.....you need to! I think it's a 1/4 inch pipe plug you need, but someone will correct me if I'm wrong. Those holes were air bleed holes, or something like that for the smog equipment on the vehicle they came out of. If you don't plug them, you will have an exhaust leak from hell when you start your motor! Nice looking Duster, so keep up the good work. :)
