I have searched the internet more broadly to find this answer but I trust you guys a lot more:

I am replacing my flywheel ring gear on my 5 speed tremec; seems like heating in an oven is smarter, i.e. more controlled, than trying to heat it with a torch.

Any reason I shouldn't heat it to 450 degrees or so without affecting the metallurgy? Or any other reason? Anybody done it this way? What was your optimal temp?

Putting the flywheel in the freezer seems like it won't help much and maybe too much of a confrontation with a too hot ring gear...thoughts?
