Is there an "up" and "down" to steel shim head gaskets? I other words, do the ridges need to be oriented a certain way (up/down)? Thanks!

I think the locating pins govern that .

I would think so too, but it can go either way.
Positive ridges go up towards the head.
It doesn't matter providing all the coolant holes are aligned. Be sure to use a cooper spray sealant.

Thanks! That's what I was thinking. Just like the valley pan.
Correct. Yes sir.
In reality it doesn’t really even matter. Even though I always put the ridges up. Kim
Same here. I’ve placed them ridge up or down. Has worked for me either way. Most of the time the dowel pins will dictate how they go.

It matters which way it goes to somebody.......
The reason it is marked is because it could be installed either way.
The dowels on a BB Mopar symmetrical.
The typical BBM composition gasket doesn’t have any markings to denote which is the top or bottom is because they can go on either way.

Not all steel shim gaskets are marked, again it doesn't matter which way they are installed.
Head and block surfaces need to be flat and copper spray or silver paint on both sides.

Mr.G no markings as to this side up.
I have always silver painted them. Kim
