Hey guys. I'm in the process of converting my standard garage door to a hi-lift door (to take advantage of my 11.5' ceiling and eventually put in a lift). I am planning on doing the work myself and ordered a LM 3800 jackshaft opener last night. I still need to size my new drums, cables and springs.
I was planning on reusing the radius tracks that I have, but got to thinking about it and am now not sure if I can. I believe that the tracks that I have are 90 degree bends. I think that with most hi-lift applications, the track is bent slightly at the top of the opening to clear the weatherstrip and then goes upwards at a slight slope to the ceiling. For this geometry, I believe the radius bends would need to be at some angle greater than 90 degrees. Correct? Can I heat and slightly bend mine? Or do I just need to buy new ones? Or am I not thinking of something? Any help would be appreciated.

I had them take mine all the way up to about 9" from the 11'-2" ceiling.
