Froze up bolt on i-250

In the process of power steering conversion, was getting ready to attach the p/s bracket. The two bolts that are in the front, I can't seem to budge them. The bottom one felt like it was going to snap off. So now I'm applying Kano Kroil penitrating oil to the bolts. Is their a better product out there, that I should be using? I also have CRC Freeze off.

What are some options to take this bolt out? Heat it up? I've nevere done this, how do i heat it up with a butane torch? And whats the process for this? Thank you all for your help.Name:  00F0F_iWt4CAqMucK_600x450.jpeg

Heat. Butane probably won't do it. Propane might. You really need a oxy/acetalyne torch. On bolts it's best if you can heat where it screws in to. You can heat to a bright (orange!) (steel) without ruining your heat treating. If you can't get to the threads and don't have a torch just heat the bolt up as much as you can and twist away.

You can try heat, and penetrating oil, and rapping the bolt head with a hammer. Spray the penetrating oil on it while it's hot. It may catch fire but it won't be extreme, you can blow it out with your breath.

Good looking engine!

Gr8 news for me I got the bolts out w/o any major issues. I sprayed them every day with Kroil penetrating oil and it seemed to work well. They were hard to get started, but after working aback and forth I finally free them loose. Thanks

My experience is that, if Kroil won't get the fastener undone- it's time for the Flame Wrench! Got a pair of studs and nuts soaking on a '35 Plymouth shock absorber. I really don't want to hit it with fire- and, I probably won't have to.

I also read that a good home remedy was 50/50 ATF/Acetone I didn't get a chance to try it out but very interested. I will mix up a batch for upcoming issues.
