5Kcstqa - head removal before upgrades at 160Kmi?

[Ben Swann]

More questions:

I will be performing some more "while I'm at it" performance mods to
5000Turbo Quattro Avant, as I have a slight but growing exhaust manifold
leak.

These will consist of 2-piece manifold, and high flow Cat and on back
Stebrosystem, additional fueling, cam, lifters.

I will be doing Timing belt, water pump & tensioner "while I'm at it" among
other PM.

Should I replace the Head Gasket even though there are no compression
problems or leaks, or should I leave well enough alone - if it ain't broke,
don't fix it.???

If it is a good idea to replace the head gasket, will I make the overall
job easier to remove head, manifolds, turbo, and downpipe as a unit and
then dissasemble on a bench???

As always I appreciate the BTDT replies.
