Changed the intake manifold, now there's an exhaust leak between manifolds.

I had to send out 2 /6 exhaust manifolds to get those exact broken off bolts laser extracted, so I could get all 3 bolts in and holding as designed.
I went thru the mcmaster carr catalog and bought stainless steel bolts and studs to put back in. Lucky I have a place with such capability about 5 miles from me at a diesel shop
