AFR 12pt vs 6pt head bolt Q

I just got the new AFR Eliminator heads. On the instruction sheet regarding head bolts it suggests the ARP 12 points. I have ARP 6 points. Has anyone had issues installing the 6 point bolts?
Should I send my 6 points back and get the 12's?

You'll be fine with the 6 points... The 12 points offer more contact area between the socket and fastener while torquing them, but either will work... I assume the 6 points are a smaller hex (kind of a flange head with a small hex?)? If so then you're not going to have any problems with clearance.. Just make sure to use thread sealant!!

Yes they're a smaller hex than the flange.
Thanks for the good news.

I guess they probably came with them, but don't forget to use hardened washers between those aluminum heads and the bolt... Otherwise you risk galling the head (along with inaccurate torque readings)..
