If I were you I would just get some reusable bolts...peace of mind.

not talking about backing them out, just torquing them down further. that 20ft-lb surely its more after the 90* turn added to the 16ft-lb

I assumed that you already stretched the bolts.

The additional angle required by spec is designed to stretch the bolt. The TTY bolts are actually treated as a spring. When they are stretched once they should not be stretched again.

I suggested 20ft-lb because this is about the limit on a used TTY rocker bolt before it begins to stretch. Further stretch will weaken the used bolt.
