Find a FSM or diagram, there is a proper sequence to tighten them down. Also I dont tighten to full torque all at once

I lost my service manual in my shop junk somewhere but I remember the torquing sequence (basically center and alternate out). Put a rebuilt engine in there about 5 years ago and it was starting to eat coolant. Just re torqued them and found the middle two to be at less than 50 pounds torque (where I started the torque wrench). The outer ones were better but of course when you start tightening up some then the others become loose too. Just finished the 65 pound sequence (going up in 5 pound increments from 50 foot pounds) and I think I'll go back out and set them at 67 foot pounds and call it a day.
