Fix the threads properly. This is a critical application and the last thing you need is for the fuel rail to pop off going over a bump or something and spray fuel on hot exhaust.
This is probably unlikely to happen, but it's not worth the chance.
Not to mention, if you use threadlocker, have fun removing that bolt to properly fix it in the future.
Also, don't forget that threadlocker is meant to be used on threads that are intact!
p.s. if it's cross-threaded, you don't need threadlocker, around here we call cross-threading 'redneck loctite'
