On the side of the stem should be the specs.
Something like 7 degree 115mm or similar.
You could go for something like a 15 degree 115mm to rise it up a bit.
You could also go shorter which will set your shoulders back and rise you up.
I don't think the top cap markings are important.
I changed mine from a 15 degree 115 mm to a 15 degree 90mm to do the same for my riding position.
