What else do I need to fix in my cylinder heads?

I'm in the process of overhauling the (failed) engine from my 1999 996 Carrera 4.  I'm replacing the short block, and reusing the heads.  The heads themselves look quite good for the mileage, with no valve seat wear.  Two exhaust valves were bent, but otherwise all the valves look good and I'm planning to reuse them.  No head cracks, and mimimal machining to flatten the mating surfaces.

Considering the mileage, is there anything else I should be concerned about, such as valve guides?  This will never be a collector car, just a daily driver, but I don't want to have to do this again.  I also don't want to spend a large fortune on this overhaul.
