Ok lm at a real loss here big time as lve never done these heads. Just got new head gasket a graphite one as l couldn’t find the au one everyone says is better Now on the gasket kit l got with paper saying what to do blah blah blah for head an block it says 1 . 30 nm 2 . + 120 deg. But both my Manuel’s say. 1 .40 nm an then 90 deg?? But then l had someone say this to me and l have no bloody idea which is rite to do but this is what l got told you go 40Nm then a 90Dec turn, it actually is 120Nm. So in reality if you go 40Nm 80Nm 120Nm, you end up with the same torque head but in a little bit smaller steps
