arp head studs , what size is the nut
#7
i never knew that..... i was getting ready to order arp studs for my ap2, since i went turbo months back, fig would hold better then oem ones...ive used them in my h22,b16,b18c builds no issue figured same quality as them. so are the s2000 bolts like other hondas, when you take head off must use new oem head bolts?becuase of the stretch?
