I put a 95 22re in my 87 runner.The exhaust manifold mounting hole locations on the head are different than the 84 22re I replaced.I have exhaust leaks, I belive from the extra holes in the 95 head.The reason I did not use the manifold from the 95 22re is because there is no o2 sensor on it.How can I solve the exhaust leak.I was thinking of finding threaded plugs for the extra holes. If I use the Manifold that came with the 95 22re how do I resolve the o2 sensor issue.

Use the 95 manifold and get an O2 sensor bung welded onto the connector pipe from the manifold to the cat...

Or get the down pipe that is behind the manifold on the 95. That is where the o2 sensor is. Use that or have a bung welded into your new manifold.
