Stripped Holes in Cylinder Head for Intake Manifold Bolts

My metric tools let me make a decent living. I get to deal with BSW once in a while too. You gotta roll with the changes. I agree with the helicoil being the correct repair procedure for a stripped thread.
That's all I used for a very long time as a line mechanic. Now, my metric tools are pushed under a work bench in a small roll around collecting dust.
