hi guys I am reassembling my engine (2200, s/n 2262, hyd lifters) after the replacement of valve guides.
the manual says : head bolts INITIALLY assembled at 24ft, check at 25hrs at 20ft - but if I removed and put back the head, should I assemble with 20 or 24ft.lbs??????
any "official" input? pete?

Not official input, but if it were my engine, I would
start with the original torque setting. You also
should see if you need to replace the head bolts.
Contact the Jabiru rep for the official skinny.

Martin,
Use 24ft/lbs for initial assembly and then check thereafter at 20/22ft/lbs.
The lower setting is simply to check for problems, not to move the bolt(s)
if torque remains at the higher value.
