Head bolt over torque what now

Doing a head gasket job on a Civic D16Y7 bought a brand new torque wrench (from the hft) turns out the torque wrench was/is faulty (won't even click clamped to a vice) over torqued a couple head bolts before I realized (The bolts seemed to get loose but still seem to be torqued to spec which I verified with a good torque wrench) what do I do now? Do I order a new head gasket and bolts? I'm worried that if I take the bolts out now the aluminum threads will come out of the block.

Fire it up and see if you got lucky, otherwise you're probably going to have to helicoil the block

Thanks for the reply I ended up loosening all the bolts and inspecting The ones I over torqued, they appear to be fine no signs of stretching went ahead and retorqued them to the correct spec I'll see how it goes. The manual actually does recommend loosening and re tightening the bolt if they make noise so hopefully it will be fine. I will double check the head bolt torque after running it a while though.

I’m very curious how this may have worked out?
