Default Stupid cylinder head bolt question - 14mm x 12-point socket?

I'm in the process of removing the heads, and noticed the head bolts (under the cams) are an "odd" shape. A 14mm 12-point socket appears to be the right fit, but I'd like to confirm before I exert the force needed to break them loose as I'd hate to strip the bolt head. I've never come across a 12-point bolt head before. Guess I'm a noob.

IIRC that is the correct socket. I know some reuse them, but it never hurts to replace those bolts with new ones....

It is 14mm-12 point for the factory head bolts. And 12point-1/2" for the ARP head studs.
