well I got the correct size bolts today from the big brown truck. There are 14 bolts in the package (which is full) but I need 16 bolts lol. Oh the joys of a custom set up.... These bolt's are the size for a Chrysler (5/16) not the standard ford 3/8 for header bolts so apparently a Chrysler only needs 14 bolts. I'm going to call ARP later today and see what I can do about getting 2 more additional bolts.
I took a few pics b/c I wanted to be sure if there is an adequate amount of threads left to thread into the head to properly secure the headers.
It looks ok, but aluminum is soft. Ideally you need 1-1/2 times the thread diameter for length of engagement. I wouldn't trust it at any less than 1 times the diameter in a pinch.
