They could help me with a sapphire engine changed the head packaging and brushing it but you can escape me I could give me the torque I gave it 18 ft/lb and then 60 °, 60 ° and 60 °
I don't know if you did hydrahulica test of your sapphira's head? It is that there are times when they crack and there they throw the water, in addition to 18 ft/lb it is really recently and should walk around 70 to 70 ft/lb luck with your repair
