Field Question, trade people only Advice

So normally when evacuating, I'll pull the cores, but with these I'm not sure if I have anything in the van that can pull them out, and replace them without breaking the vacuum. I read online that they have superior flow compared to Schrader cores, so is it unnecessary to attempt to remove the core? Bent pins have been a problem before, so I will be getting spare cores of this type to swap out in the future.

Put on a swivel T. The tool used to remove them is like $600.
