Ok so I am getting ready to put in my ARP 10mm head studs on my motor and I would like to know what size Allen Key to use, I know a couple fit but I want to know what have people used so they dont strip anything. I searched for this but couldnt find it, and I have to go to work so time is short.
Thanks for your help.
