Try finding some valve lapping compound. It is a gritty paste that you put on your allen. It often will take up enough of the slop to allow you to get the bolt out.
If your allen is worn also try using a hex head of a similiar size, It has more surface area and grippers.
ALWAYS whack an allen an extra time to make sure it is fully seated. Always, double-whack an allen to make sure it is fully seated. Check the head also for dirt and debris. If in doubt: clean it out.
If your allens are worn, throw them away or grind down the ends so you get a clean perpendicular surface.
