Just about to do the head gasket and need to know the torque for the heads. I've seen a setting which uses a dial gauge and one that uses only torque figures. Which is best and is it true that the middle bolts are tighter than the outer ones.
Thanks in advance

 

the midle bolts are slightly more torqued up. by im sure 15'
once torqued up, its degree terns on a torque wench

i'll try and find them later for you mate

 

Then tighten torque and angle in the following stages, in the sequence above
<-front
3 1 6
5 2 4



1. 29 N/M OR 22 FT/LB
2. 69 N/M OR 51 FT/LB
3. BACK OFF 180 DEG. (REVERSE SEQ 6-1)
4. BACK OFF FURTHER 180 DEG (REVERSE SQ. 6-1
5. RE TORQUE 29 N/M OR 22 FT/LB (1-6)
6. 80 TO 90 DEG. (NOT OVER 90)
7. 40 TO 45 DEG. (NOT OVER 45)
8. NO.1 AND NO.2 40 TO 50 DEG. FURTHER (NOT OVER 50)

Step 1-2 are basically for settling the gasket, as step 3-4 pretty much take all the torque off. Put a little bit of oil (or better still a small blob of moly grease) on each bolt thread.

Don’t guess the angles. Get an angle disc for your torque wrench.
