Just read ARP chromoly bolts are heat treated.. problem solved.. (for me at least haha)
Plus these only need 15ft/lbs max and these ARP bolts use a 3/8" hex head so the bottoms will be easier to get to then the 1/2" nut of the norm.
you have to remember the flanges are 1/2" thick, then you have to account for the spanner washers which are at least 1/4" thick and the threads in the head are at least 5/8" 3/4" deep
Summit part numbers- (washers are also included and I plan on using them)
ARP-154-2001 -SBF 2" under head length intake bolts (12ct you need 11)
ARP-651-1250 -1.25" under head length bolts set of 5 you need 2 for exh. mani. ends
these 2 sets are $37.. you won't get individual ARP bolts cheaper than this..
