Putting it back together

Need some help?
I’ve done a search but couldn’t find exactly what I needed. I’m putting the head back onto the piston and wanted to make sure I don’t mess it up. Do the piston rings need to be positioned in a certain way in relation to the ports or each other (or) can I just pinch them closed and fit the head and piston together with a little oil?
Thanks

Thanks......see exactly what you mean. I've heard about Molly coated rings etc.....should I wait and get those ?
