Which way does the exhaust gasket go?

When installing Fel-Pro exhaust manifold gaskets, if there is a smooth, metallic side and a composite side, the metallic side should be installed facing out, meaning toward the exhaust manifold.

.

Keeping this in view, can you put a head gasket on backwards?

When you have the gasket on backwards, you're not cooling the block on that side. As a result, your engine can be roaring hot, making tons of steam, and the water going to the radiator can still be relatively cool.

Also Know, what side of the head gasket goes up? The edge of the gasket with the Up stamp must be kept up toward the top of the engine block.

Considering this, do exhaust gaskets need sealant?

You shouldn't need to use sealant on the gaskets. Most exhaust manifold gaskets either come with their own sealant (like Fel-Pro's do with the silver looking stuff), or they are metal and don't require it either. If you don't, you could have slight low spots in your manifold which could allow for exhaust leakage.

Do you put silicone on a head gasket?

Yes, some method of sealing is required if the engine will be running coolant or oil through the head gasket. Since most engines run coolant and oil through the head gaskets we'll discuss head gasket sealants. Most importantly, you don't need very much; second, don't use silicone.. that about covers it.

Should you use RTV with a rubber gasket?

Using RTV on the gaskets with fluoroelastomer coating or silicone sealing beads causes multiple issues: The sealer can chemically attack the rubber sealing beads and degrade them.
