Locking header bolts

I have Stage 8 header bolts with locks that go against the header tubes on my 306. Now, someone told me I should retorque my header bolts after the new motor's first heat-cycle. But they didn't know I had locking bolts.

So my question is, should I:

A-torque them now, install locks, forget
-or-
B-heat cycle, then torque, and install locks
 
Heat cycle and tighten up in a week or two.

Over time, they will stay tight longer.

My 79 has had headers since 1987 and I don't need to tighten them but a couple times a year.

I used allen head bolts so I can quickly get on them to tighten them.
