George,

If you are using the Elecraft MH2 (or Proset-K2) or other high output 
electret type microphones, then you do not need those mods.  If you will 
have the KPA100, then the mods are not needed.

If you will be operating the K2 as a QRP SSB transceiver and will be 
using a lower output microphone, then yes, you would find those mods 
worthwhile.
I would not install them on a routine basis, particularly the KI6WX 
Increased KSB2 RF Gain Mod - even the original author now states that it 
is completely unnecessary when the KPA100 is to be installed because the 
KPA100 does have reserve RF Gain while the base K2 may be marginal on 
some bands, particularly 10 meters.

73,
Don W3FPR
