Two years ago I pulled the heads and water gaskets off, cleaned them and put them back on with new gaskets. It appears that I'm getting a fair amount of leakage now so I'm going to do it again. This time I'll check for head warpage which I didn't do last time. First question is on the torques. According to my manual, when replacing each, I need to torque the bolts twice. For the head it says 11 ft-lbs and then 22 ft-lbs. For the water jacket it says 35 in-lb and then 70 in-lbs. The torques that are stamped on the head and jacket say 3.0 kg and 0.8 kg which work out to 22 and 6 ft lbs, correct? Those are both pretty light but I'll do it again. Any suggestion on a torque wrench that does in-lbs?

Also I noticed that I'm also getting some seepage around the bottom of the block. Any suggestions on that?

Also, no gasket sealer, correct?

All outboard heads are warped after 10 years of use or more.----Resurface them with emery on a piece of glass or valve grinding compound on a piece of glass.----Those tork values are correct I believe.
