Valve Relief in top of pistons
Engine: 1990 300E M103
I am in the middle of my engine rebuild and I was wondering about those piston valve relief notches. There is one shallow valve relief notch and one deep notch in my pistons. Can someone tell me which notch is for which valve. I assumed that the larger valve relief notch was for the intake valve given that it is larger. Am I correct with this? Thanks guys!

That would be a BIG yes, larger notch is for the intake.
