The head on my 350 N2 on my new project has been welded (quite a lot) without stripping it and i don't want to just yet I cant tell why, runs great but will change it as some point, can I only use 2ua or are 31k's etc the same?

Hi Andy
What is the head actually marked as?
31k Y1,2 and 3 were on UK bikes
Ideally you want a Y3 as it will have the correct tapered temp sender thread
There are 1ua heads that the UK never got which had a different squish band, no idea why we never got them unless it was for lower fuel quality

Oh and by the way, I've never seen the illusive 1ua head
Don't know anyone who has, only the pic on Xaviers site
