SpaceX has switched to a new generation of engine bell covers.

There is orange and orange and white tape on the parts and the booster indicating previously flown hardware.

There are some engine bells that are still warped. SpaceX has determined that the warping of engines does not matter or the engines will unwarp during test firing and other operations.

Raptor engine 314 which flew on Booster 12 was already reflown.

There was a successful static fire of the recovered Booster 14.
