The OEM head bolts are not torque to yield. If they where installed right the first time they did not stretch. Clean the threads good before you install them.
uhm, anytime you have a low fixed torque spec, and then subsequent "degree" turns, the bolt is a TTY.
The factory head bolts are TTY. thats why honda says use 22 then 2- 1/4 turns, if the bolt has been used once. if new, 3- 1/4 turns. that bolt is being stretched during those 1/4 turns.
The stock bolts have a better expansion rate than do the arp studs. while i like arp studs, and put them on everything, this engine doesnt seem to like them. (not my experience) ive seen several others with odd results. I have to assume operator error during install, but just in case, ive stayed clear of them in my s2k engines.
on S2000 bolts. I've done so many honda heads that I didn't even think about it. My bad.
