Stripped threads

[sssammm]

Just putting my inlet manifold back on and 2 of the bolt threads are gone, any quick fix, or do i need to helicoil them?

I have a helicoil fitted on one of my i/l manifold fastenings - it's a good alternative to oversize tapping.

Yep, drilled the old thread out, tapped and fitted a helicoil, now as tight as scrooge
put the whole thing back together tonight
