Some equipment I installed mentions form 337 - for example VOR/LOC/GS receiver,
IFR GPS, etc., Is 337 required in a new kit project? It is for "Major repairs
and alterations".

337's are not required for alterations to homebuilts. You are required to "notify"
the FAA of changes in the design (this will be in your operating limitations). No
A&P, DAR, or anything else is required.
