Read on www.landroverclub.net/Club/HTML/Overheating.htm about supposed design problem with heads, that can lead to overheating (see below). Read elsewhere of a guy that torques this 3rd row of bolts to 50% of recommended torque.

Anybody here removed the 3rd row of bolts?

"6. The cylinder head gasket.
Hey, that's my favorite one. The Rover engine has a special design fault in his heads.
The heads are held on by 14 bolts. The problem lies in the bolts 11-14. When they get tightened they put an load on the upper bolts, raising the heads by a slight amount..." etc.

Yes, the 3rd row of bolts was eliminated with the new head gasket. So, I guess it stands to reason that you can remove them or at least back up on the torque.

All heads cast after June 15, 1995 do not even have the holes for the lower row of bolts.
