Which way does the head go on?

[marked23]

On an OS 91 csps, the head goes on with the oval glow-plug cavity parallel to the crankshaft.

But that still leaves two choices for orientation.

On the head there is a cutout for a remote glow wire on one side but not the other. This cutout could face to the spindle or to the back of the engine.

Which way should the head go on? Does it matter?

It doesn't matter unless you are going to use the slit cutout for the remote glow adapter. If you are orient it so that you can use the slot. Otherwise I think the stock position is towards the backplate of the engine.
