I used to have a RB25 in my s13, the day after I got it running that bolt snapped and bent 22 out of 24 valves. it ended up costing me $650 to get the head rebuilt.
I don't know if I over torqued it, or what, but it broke, and it sucked.
it also says to replace the bolt in the FSM whenever you replace the timing belt.
a grade 8.8 bolt from ACE is the best $1.50 you could spend. lol. it could save you alot of money.
