10 Day Magnum Swap - '65 Dart 270

Ok thank you and no problem. Sorry I'm asking you so many queastions but its my first magnum swap. I pulled engine again and pulled pan and resealed them. I have a set of summit headers I was planning on using just wasn't sure if I could squeeze them in with engine bolted in. Turns out no, no you can't. SO engine will be lifted back up a third time.
