hex head bolts stealth heads are there any for those aluminum heads? I know the head needs to be smaller than stock size but really want the hex head look. Anyone know?

arp make both 12 point and 6 point
they won't have correct head marking but you will need the washers that come with the arp's
440 source also sell's a lees expensive set (half the cost of arp's)
but not sure if they are 6 os 12 point

These should work for you!
