Something I guess I didn't mention in my earlier post, is that the valve bodys sold by Axiom are rebuilt units which have new Sonnax valves in place of the older ones. This will take care of the need to do both. Plus, I personally think the Sonnax valves are a little better. But that just might be me.
Ziyad is right though, if you go back with an OEM valve body with OEM pistons, you will be right back here fairly quickly.
Yes, I would do the TC too. The clutch material of the TC is basically metal, so once it slips a few good times it could be damaged. Why take that chance, unless you really really have to? Check around at your local parts stores and you should be able to find rebuilt units for around $100.
