Is it sufficient when installing the cross over pipe just cleaning and installing new O rings then seating the pipe or should I also use some gasket sealer ?

O-rings only. Make sure to clean up any corrosion on both the head and the COT and slide it in. Lubricate the O-rings with oil or di-electric grease.

I used both on my recent removal of the COT, better safe than sorry...
And if you cant find the O rings from ford, #20 O-rings from most hardware stores will also work.

Never ever use an o-ring from the hardware store. They will leak sooner than later.

I thought I was the only anal one that doesn't mind the price/waiting if need be.
Just too much of a PITA to fix after the fact.
