HEAD GASKETS

Which side goes up on a cylinder head gasket? The steel ring around the cylinder bore is wider on one side than the other side. I'm thinking it may not matter, but I'm putting the wider side facing up so it is against the cylinder head.

Good question. Most of the time it will be printed on the gasket which side is up.

So is it the opposite for the sohc?

No. The number of cams an engine has has nothing to do with which way the head gasket goes on.

SOHC head gasket will only fit one way. The cam chain tunnel is actually a little offset and the two 6mm bolts there will show you when the gasket is right.

Of coarse shinyribs is correct, the same goes for the cylinder base gasket, the head gasket and valve cover gasket. I was there with all three just last week. All back together!
