Froze up bolt on i-250

[sambudo]

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.
