If and when you go to work on the 2.3, get a thick pair of gloves as there are more sharp edges on that head than you care to find. You will need a lever type spring compressor, and something to push the cam follower out of the way, off the top of the valve stem and off the top of the lifter. It is one of those jobs where you are looking to keep your fingers out of the way of sharp and metallic objects for fear of squishing them or taking chunks out.
I used an old valve spring compressor that had a reversible hook on the end. It has been quite a few years, but I remember doing something where I turned the hook upside down, or changed how it was bolted to the arm/lever part of the compressor. Keep the followers in the same position when you reassemble as they are just like lifters in their 'relation' with the cam lobes.
I still vote for a delay - at least until it is warm outside. And proceed only if you are getting spark plug fouling. Mine doesn't foul plugs, and uses about the same.
