Default OS 46 FX Question for Bax.

I just rebuilt an OS 46FX engine (new bearings) and noticed that when reassembling the engine that the fit of the piston at TDC changed slightly with how tight the head bolts were. Do you know what the proper torque (in inch-lbs) for these head bolts are? I have a proper torque screwdriver to do the job.

You  just get the head bolts good and tight.  There isn't a torque specification.  Yes, the feel of the piston/liner fit at top dead center will become tigher when the head is tightened-down.
