Getting ready to swap a 5.7 into my 73 Dart Swinger

What do the pistons look like? Any contact? I can understand your frustration with the costs of doing this.
Yes there was some contact I made a video but here are some photos. Intake valves on both heads are all toast. Piston damage seems to be very little. Screenshot_2019-03-15-07-52-54.pngScreenshot_2019-03-15-07-53-33.png
