Don't rush, spray deep creep,  try to loosen AND tighten BUT just a little bit, repeat about once a week for a month. Helps a lot those small stresses over time.

^ that didn't work for mine
Had to drill and tap, well drilled the first then started tapping for the bloody tap to brake off, so back to square one on that

sorry to crash the thread but I took inspiration from it and wanted to see if my header bolts would come lose yesterday. I couldn't get my size 6 allen wrench into them though. I was going to try and force them but I'd though I'd ask first. Is that the size wrench the take? Perhaps it was just rust in the way or they have contracted maybe?

It does take  a size 6, give it a little tap and it should go in, be sure it's completely in, otherwise you will round the head.
But if the bolts are rusted to this point the chance you will have problems with some of the bolts is huge

Thanks. Might buy some new bolts and give the job to a mechanic so.
