I'd go with the "slacken everything of" approach. Aside from the headlamp mounts, your main problem will be to try to keep the crank looking symmetrical and evening out the disparity of the bonnet ends.
The other approach is to take everything off, perhaps including the cow horns and assemble the body panels without the radiator. You may find that some of the holes are oval or elongated and this may allow better alignment. Sometimes making a hole 1/16" bigger can give a surprising amount of compound error at some distance.
Wait for a day when you have nothing else to do and start early without a deadline to finish to give yourself the best possible head for the job.
If it has never been correct since you bought the car it maybe that it has never been right at all, I've seen some truly grim shut lines over the years. Not everyone is as particular as the next man!
