Hi the reason that I asked about the bolts was because there are 2 different kinds. One is Torx head bolts and the other is hex head bolts and the torques are different. Also if you are putting the head back on youhave to tighten the bolts in a certain order or bad things can happen.

The order of tightening is as you are looking down at the head on the passenger side.

12 10 4 2 6 8 14

13 7 5 1 3 9 11

This is for torz head bolts, it can be done with the engine being cold and there is no time that you have to wait until you do the next stage.

Stage one 22 ft-lb
Stage two 90 degrees
Stage Three 90 degrees



This is for hex-head bolts

Stage one 29+4 ft-lb

Then wait 15 minutes

Stage 2 44+4 ft-lb

the run the engine until fully warm(about 25 minutes)

Stage 3 25+5 degrees



I hope this helps.

Andy
