The chiltons manual I have suggests that the head bolts be torqued in a sequence that starts near the back of the engine and then moves to the front and then slowly converges to the middle. This is the opposite to virtually every engine I have ever come across before. Most start in the middle and work to the ends in a sort of spiraling fashion. This method avoids buckling of the gasket in the middle as it is torqued down.
The toyota manual I printed off the net and all the 4M 5M manual's I have say to do it from the centre outwards. This is the way i did my 7M with factory HG and my 2 4M's and haven't had a problem.
