Im working on a 360 and the previous owner drille out the threads for the bolt holes along the top row in the heads on both sides for the exhaust manifolds. Has anyone used heilcoil or timesert? Thanks
I've fixed several of my own using 5/16 grade 8 bolts with nuts on the back. It looks a little hillbilly but you'll never have to deal with seized/broken bolts again.

Out at PnP once came across a 1960 T-bird fe 332 or 352 that had cut out all the upper threaded boss and use Tee bolts dropped between threaded cut out slots with nut on the manifold side. Look like it worked pretty good.
