head bolt torque specs and order on 2002 Isuzu Rodeo Sport

A friend of mine broke the timing belt on her 2002 rodeo she put a new timing belt on it and found out when she tried to start it it would not run.We ran a compression test and found all four cylnders to be very low. Most likely she has some bent valves. What I need to know is the order and the torque specs for when I put it back together. Any help would be great.
