where used for about 550 miles while a motor was being broken in. where purchased brand new from honda. where removed and replaced with ARP studs after the motor was broken in and boost was added. these have only been torqued once, to 49ft lbs. i paid $9.xx each for them, i'll sell all 10 for $50. i can get pics if you want, but we all know what a head bolt looks like.
