Default Valve relief location

Does the valve relief on these piston go upwards or down.

I would assume the laser etched serial number would be faced upright, but I believe the valve relief should be closer to the valley plate rather than the headers.


Any opinions?

Pic 1 or 2... which is correct

Valve reliefs go up, towards the valley. FACT.

Why do you think they would have put the sketched number so it would be upside down rather than right side up?

I have no idea. I just know that the engine won't care about the etching, just where those reliefs are.
