Anyone know what socket it is I need to remove these. My old engine has them in and I want to strip it but I dont have the correct socket. It looks like a star but I dont know what size or what its called? I do have some star sockets but this seems to have twice as many points?

 

The ARP head nuts come in two different sizes, 1/2" and 9/16ths both needing a 12 point socket to remove them.
Think the head studs take a 1/4 or 3/16ths allen key to remove them.
Hope this helps,

Mick
