Intake hole please help

Yeah I thought I would have to get another manifold, but then I have to get new bungs, get it machine for the injectors and find a machinist that can take off the wee bit I need to clear my TPS. Could I get a patch welded over it a little bit at a time to stop it warping? These manifolds are rare as over here in New Zealand. I had to import the injector bungs and fuel rail from Ross Machine Racing. I hasn't been a cheap job and I dont want to throw it all away and start from scratch again.
