Someone mentioned this in a thread recently and I can't remember where.

It was suggested that one option for reducing hood spring tension was to open the hood, open the door and point a propane torch onto the spring and get it good and hot until it starts to unwind a bit.

If this really is a reliable method, it seems like by far the easiest solution to the age old question of "where do I find low tension springs?" A question that is becoming more difficult to answer now that the vast majority of K-Car donor cars have been melted down and turned into lawn mowers, twisty ties, abstract welded sculptures at Burning Man, and Kia Forte Coupes.

Has anyone actually done this torch method? Was it done with the original hood on the hinges or off?
How do you know when you've heated them enough? Is there a worry about uneven heating (getting one spot on the spring hotter than other parts)? Is it hard to make the springs even between both sides?
 
Take too much tension off and it will become a lift-off hood.
 
We'll, I can see one way this could end well. However, I see 43,674 ways that it won't.

Which is exactly why I'm asking for the sage wisdom of the forum. :D

It may not be crazy though. It is pretty easy to isolate the areas being heated with the torch, don't you think? How many of us have resorted to the ol' flame wrench when battling with a stubborn nut...and somehow not burned the car to the ground. :D

unless you're running a fiberglass hood, where's the need to even do this? Be easier, quicker, and less dangerous to use the ford explorer strut conversion method
 
How would you know when to stop? I think once the hood starts to drop its going to close.
I've witnessed heating coil springs to lower a vehicle. The heat is directed at one coil of the spring at a time. It would be quite difficult to do that at a hood spring.
