If it is the K series engine
Headbolts are tightened to 1st stage - 20 Nm or 15 lbf ft
Then turn thru 180 degrees(2nd stage) and then a further 180 degrees(3rd stage)
Make sure you tighten in correct sequence
. . . . .
9 5 1 3 7
. . . . .
10 6 2 4 8
dots denote headbolt location - numbers are sequence to tighten in

Its not that critical. Do the nuts up working from the middle outwards and from one side to the other and do a final tighten up in the same order using a fair amount of strength until they feel solid. Run the car for a few miles and then try to tighten again - they may go a bit more.

As Jamand says but make sure you use new headbolts, you wouldn't want to snap one and have to start again.
