is this an ARP headbolt ?

[24vtoy]

Hi Guys

sorry for the noob question

I wanted to know if my 7mgte already has ARP headbolts fitted but without removing the headbolt can anybody tell if the attached picture is an ARP headbolt or a stock oem headbolt ?

I don't have a BHG as yet but want to plan some upgrades soon

thanks

Those are stock bolts. ARP bolts are 12 point 1/2 inch.

to be exact my good sir 3/8 deep socket 14mm 12 point.

Only for studs. The picture concerns bolts which are 1/2 inch.
