Which way do the blades go back into the slot- With the numbered side UP or DOWN? Or does this not matter? I decarbonized those bad boys now they look new again. Please advise!!!!!

On my 2003 XC800 the numbers face up. Other than the numbers can't see any difference in the valves from top to bottom but I still make sure I put them in the same way they came out (numbers up)
