Torching the SPRINGS
or
This will cause the spring to loose it's temper. It ruins the properties of the spring steel (where it was heated). It can lead to cracking and other types of failure. I'd rather see you cut the springs than torch them (and I absolutely don't like cutting springs!!!! if that gives you any idea).
These are just my thoughts....
But, if it were me, I'd run away.....
It was pretty common back when my dad was a kid and aftermarket springs weren't readily available.Your average car guy didn't know jack about spring rates so they cut springs with torches and/or heated them til they sacked out.
My opinion is either cut your stock springs(with an abrasive wheel)or get some aftermarket springs.
