red underbelly, help?

He may be healing. If it doesn't look like it's getting worse, then leave it be. Don't pick him up, and replace his substrate with something soft. Snakes underbellies are sensitive.

I know it's debatable, but what's the best substrate to use then?
I was previously using reptibark, but I switched to Aspen shavings.
I know not to use newspaper print or gravel bits.

I use coconut shred. It's pretty soft.

The type of heater doesn't matter any heater can burn. There are a huge range of things this could be a burn is the most obvious. You need to know your temps! Just using bulb and guessing is not enough you should know the air temp inside the enclosure (74ºF is a min suggestion) and a hot spot temp (90ºF is a typical one cooler for baby ball around 88ºF) and a surface temp on the cool side (ideally around 80ºF)
