Snake introductions

So my adopted male is going to be out of quarantine soon. I want to be able to have him and my female out at the same time so I was just wondering if there is anything I should know about having them "meet" for the first time? She is only 420 grams and he's 1400. Never had two snakes so just thought I'd ask

I've had a couple of combinations of my snakes out together (2 at a time), but they've always been of similar size. They should be just fine though, just keep an eye on them.
