Rounded out

Just pulling the heads on my X2 and the cap head down the pushrods tube has rounded out despite me using an unbrako Allen key. Any suggestions? I have 3 ideas at the moment but interested to see what comes up.
Considering all the other things I have found over the years I am still tempted to ascribe the PO to this one, and not looking forward to what I will find if I have to go deeper.
Cheers
David

Try the next size up torx bit. You'll have to hammer it in, but it often works.

The next step is to drill the head off. If you use a left hand drill bit, then there's a fair chance the drill will grab in the fastener and just unscrew it.
