I have 3 that I've been afraid to attack for 6+ yrs. He makes it look easy.

LOL, he's going in hardcore with that torch. Recently had to pull off the manifolds on a 2003 Hummer that had been on for 22 years. Used one of those small butane pencil torches.... Doesn't take too much to take care of the factory loctite..... Then with a small ball peen hammer I would tap each one lightly about 15 or 20 times after spraying it with penetrating oil. Only had two or three that I had to rotate back and forth left and right a couple times. Other than that they all came out nicely. But .... It had never lived in the rust belt. I imagine for a shop considering the time factor, the big torch would speed things up quite a bit.... Just seems a bit risky to me.

I do have a nice drill guide that bolts onto the head, and a set of reverse drills. So far they're still sitting unused.

I had 2 broken on my 06 Suburban. I was ready with my welder. I had removed them on engines on engine stand before by welding a nut, but never on an engine inside the vehicle.

When I removed the exhaust manifold, there was plenty of threads so I was able to just unscrew them with vice grips. I bought some Summit Racing bolts that kinda looked like ARP stuff. I think they were like $25.

I really miss being in a shop where I had access to the "hot wrench" and a bigger compressor than a 3 gallon tank. Have to be cognizant of the neighbors. With no rust here, the "hot wrench" not being available is really not that big a deal and the small compressor works for cleaning/blowing stuff out. I have the Milwaukee Tool battery stuff and that works fine. There has been a couple times an air chisel vibrator or cutting bit would have been nice but I worked around it.

IMO, the video guy got real lucky with the small amount of rust he encountered.

I have clamps on 3 corners of the engine and no leaks/noises but when the time comes, I will prep for 2-3 weeks in advance with Aero Kroil on all the nuts/bolts.

I have 3 bridge clamps on mine too. I should leave well enough alone.

Did GM really use thread locker on steel bolts into an aluminum head or was he just kid’n?

The ones in my 2012 didn't have any thread locker on them from the factory. They all came out easily, thankfully.
