The barrel was pulled from an upper and it has the two cuts from where the pinned FSB used to be. I can't simply use a low profile gas block and set screw it in right? So what are my options?

Sure you can.
The Spikes barrel I bought off EE had the cuts filled with a metal filler, then just has a Vltor low pro block with set screws. Only the rear screw actually sits over the rear cut. The front is untouched by the block. Or just use a clamp block.

Yeah I didnt mean to insinuate you NEED to fill the cuts, just if you wanted it to look flush, as a lowpro block wont cover the front cut.
Mine is dimpled on top of the rear cut and dimpled for the front set screw. That is definitely recomended, as its quick and easy and will keep it from moving at all.

It looks like the rear hole will fall right into the rearmost cut, while the front cut will be exposed. So I'm good to go right? I'm okay with the exposed front cut as it'll be covered up by my rail anyways, but out of curiosity, what metal filler would work well filling it? I have no experience whatsoever working with metal filler.

They make "wide", "long" whatever gas blocks specifically to cover those, YHM and other make them, forget who else

My recommendation would be a clamp-on gas block, helps avoid any Issues...Good luck.

This works well & covers the grooves from the taper pins: http://www.laruetactical.com/larue-tactical-low-profile-gas-block-lt-202

why not just buy a used fsb and shave it down? if you have a bench grinder and a dremel you could have it done in 30 minutes.

Yeah if youre on a budget and already have a FSB this is a good route.
It will be covered by your rail you said so looks wont matter, not that they look terrible when done right.

Why go ghetto when you can get a gas block that is designed for what you have....

Because it's very unlikely a used fsb will have the holes drilled in the same place as his barrel slots (each individual fsb is drilled and mounted to an individual barrel).

Me too, if you don't mind the front slot being exposed I'd just go with a Daniel Defense clamp-on (or Vltor, or maybe the YHM pinch screw if you have room under your handguard).
