Working on a 500 fuji motor and trying to find out the torque on the head bolts and not that " take them down three times back them off half a turn then tighten then two turns...." crap all this still comes out to a number in footpounds.

its both ft/lbs and crazy directions, they're very similiar to torque to yield bolts
**TORQUE ALL BOLTS EVENLY
IN A CRISS--CROSS PATTERN
1 -- Torque bolts to 22 ft. lbs. (30 Nm)
2 -- Torque bolts to 51 ft. lbs. (70 Nm)
Leave at this torque for 1 minute to allow
gaskets to seat for proper sealing.
3 -- Loosen bolts evenly 360º (1 turn)
4 -- Torque bolts to 29 ft. lbs. (35 Nm)
5 -- From this point, tighten bolts
evenly 90º (1/4 turn)
6 -- Finally, tighten another 90º (1/4
turn)
7 -- Install two 6mm bolts and torque
to 6 ft. lbs. (8 Nm)

Good lord :eek:

It would be a good idea to replace these bolts, if you are concerned about getting an accurate torque on them.....
