Depends on what right you are talking about. The right hand side facing the engine from the front or right seated in the vehicle. You'll need to specify.
Exhaust gases.
On the exhaust header. Normally the drivers side. On the exhaust header. Normally the drivers side.
Between the exhaust header and the catalytic converter.
Header or headers are a high performance version of an exhaust manifold
It is in the exhaust pipe between the header and the catalytic converter. That is, it is downstream from the header, and upstream from the catalytic converter. The first O2 sensor is located under the hood on the driver's side. It is located in the exhaust pipe between the header and the catalytic converter. The second O2 sensor is located in the exhaust pipe between the catalytic converter and the muffler. The wire runs up through the floor board where the connector is located under the carpet under the driver's seat.
The exhaust manifold is the header that starts at the piping on the driver's side of the engine and runs back out to the exhaust.
i header is much better than a manifold better it will give you increased air flow horse power and gas mileage
Yes it sure can and will if the valve covers are leaking oil and the header gaskets are worn out/ leaking.
The exhaust valve, the exhaust manifold, the header pipe, the catalytic converter, the muffler and the tail pipe, not to mention the clamps and hangers.

It is not worth the effort since it will probably just crack again; cast iron does not weld well. Use this as a good excuse to put on a header. I got a nice stainless steel header for my 1991 4.0L for $185 including shipping. The exhaust manifolds are also known to crack. If you do not want a header, another option would be to watch for someone that did put on a header but is trying to get rid of the stock exhaust manifold they took off.
