ETA engine head bolts

[Mkeisler1@xxxxxxx]

Does anyone know if the ETA engines have the same problem with the head bolts
breaking as the 535i's do?  I'm going the adjust my valves soon and would like
to know if I should go ahead and change them to the Torx head bolts.  If so,
does anyone know the part # or spec for the bolts?  Should they be tightened
to the same torque rating as the factory bolts?

Thanks in advance--
