I’m not sure why this video popped up in my suggestions. But having done at least 30-35 header swaps on LS motors, I can remove them all without snapping any in about 15 min. (Engine out of vehicle) Step one, spray with some kind of penetrating oil. Let sit for a day. Step 2, air hammer with a pointed bit and hit straight in the center of stud or bolt for about 2-3 sec ea. Step 3, tighten ea bolt about 1/8 of a turn. Step 4, 1/4” air ratchet and loosen all the way out. The air hammer shocks the bolt and any rust buildup inside the heads. Tightening the bolts stretches them slightly and prevents pulling threads out of aluminum heads. Learned this trick from a machine shop.

Liquid Wrench has those instructions on their cans and has for decades. Tap the bolt with a hammer and the vibration helps the penetrating oil to work itself in and dissolve the rust. I always start by tightening frozen bolts a bit first before backing them out. It works. Always spray more penetrating oil in with each in and out torquing to help flush out the dissolved rust in the threads which wedges the bolt stuck.

Penetrating oil doesn't help at all, that's a myth. I heat them with a torch til they are glowing red and remove them with a crescent wrench. The crescent wrench allows me to get a good bite because it's adjustable.

An old fella told me that loosen and tighten trick, haven't snapped any bolts since!

When backing the bolts out a bit, keep spraying more PB blaster under the bolt heads to help flush out the rust and loc tite before tightening them back in. each time back and forth it will pull out more rust and free up the bolts. Also using compressed air with a blow gun also helps displace the rust from between the threads, then apply more penetrating oil.

That definitely sounds like it would help, I will give it a try next time, I always enjoy learning new ways to tackle things. Thanks for the advice and thanks for watching!!

Very good ideas! I've got a pair of 5.3s, one in my 83 Camaro and one in my 04 Tahoe. When I did the engine for my 83 Camaro it had 2 broken ones that I got out w/my welder. The other ones I did it this exact way using both of your methods. When I re-install everything I like to use the longer size stainless studs from eBay (can't remember length but I think it was the longest ones I could find) and a ton of anti-seize on the stud. Works like a charm for removal!

Real good advice. I knew these things but wasn't really thinking about this. Thanks guy!

Tighten and then loosen. Breaks the rust

You can build them up with a mig welder if they break down inside the hole, then after building the weld flush with the surface you can weld a nut to it and wrench it out. Not really a huge issue, but obviously better to get the stud out in one piece.

The ujoint was stuck in the yoke and I was in proces sof freeing up when he thought he could put a 12 sided wrench on it when I said only 6 sided and round it be.. now I can reach it and could have taken it out.. we do not need heads so about to cut that bolt off.. but will try some bolt extractors sockets I have 1st in morning.. this whole design is not mechanic friendly, having to pull pulley off PS pump to access bolts, putting that accumulator on the AC lines on top of compressor blocking bolts to bracket, and tucking motor under when it could have been forward a few inches allowing us to reach those ground cables and other electrical at rear of engine.. think will pull intake off before yank out as replacement motor had its manifold cracked by salvage yard and we cannot risk damaging in process...

Dude you are preaching to the choir on placement, they should make some of these engineers wrench on this stuff so they see how ridiculous it is to spend 30min removing parts for a 3min job on something simple! I wish you luck on getting that bolt out, I have used a reverse drill bit with a 90 degree drill adapter to remove them before, it's a whole bunch of not fun!!

Doing a light build on my old 04 escalade winter beater. The manifolds have never been touched. While doing a deep cleaning under the hood I noticed the head is missing on the driverside closet to the firewall. I made the responsible decision and ordered a set of long tubes and new ARP stainless hardware. Ive been soaking the hardware for a couple weeks now mainly procrastinating the job. Im hoping there is enough stud hanging out of the head to weld a nut on. Worse comes to worse it'll give me an excuse to pull the heads for some 243s, upgrade the rockers and slide in a very streetable cam.

It may help a bit, but when you heat the whole motor the block expands with the bolts too. Best bet is to try the tighten loosen approach first if possible. Best of luck, be safe, working on hot exhaust is not super fun.

Most things I work on are a 100k + miles so I am not sure to be honest. I think a lot of it has to do with the number of heat cycles the motor goes through, regardless you always want to be careful with manifold bolts high or low miles, just because its so annoying to drill one out if it snaps.
