Question Using a Torch on LT4 Intake?

As I continue to battle trying to get this vacuum fitting plug out of the front of my intake that the previous shop put in, after trying to JB weld a nut onto it twice and that failing to get it to budge, I'm thinking the morons used red Loctite on this.

Looking over info on it, it appears it takes a lot of heat to break that down (500 degrees). I used my propane torch a little on it last night, but I don't really know how hot it got yet. But my question is if there's anything I should particularly worry about applying a torch right onto the intake. I could imagine some paint damage but at least that part is hidden by the throttle body and the thermostat.

Any thoughts on this?

Yeah. The paint is gonna be screwed but if you take your time with the propane torch it should work fine. I use one to remove seized bolts in aluminum quite a bit.

Thanks for the info. It sucks, but I think I'd rather try that than drilling into the intake or removing it and risking causing a leak.

You probably could use map gas. Its a little hotter than propane. If you can get a hammer to the plug hit the plug its self a few wacks. That will do wonders alot of times.

Heat and impact go a long way.
