You can treat it as an Section VIII Appendix II Flange. Hopefully the two stud bolts that you cannot insert, are 180° apart.

 We have the following  scenario in one of our projects . Due to
inadequate space availability caused by the valve body studs, the
piping flange studs could not be inserted into the flange joint.. The
case in question is a 10" , 900# Flange which carries 16 no.s studs.
It is not possible to insert 2no.s stud bolts in the flange joint.
Does B16.5 mention anything about the safety / operability / validity
of a flange joint which has two no.s stud bolts less in a 16 stud
flange joint ?
