Yep. Seen guys heat the bottles with a torch. I stayed far away from that.
Anything over 150hp and no doubt timing needs to retard. But any motor on gas is borrowed time. You can't make that type of power increase and not expect more maintenance. Part of the deal...

For what you are doing, heating the bottles may be overkill.
You should have enough ignition, but you may have to close the gap down a bit. You'll also need a way to pull some timing out of it as add the nitrous.
And, you may want to use a progressive controller to run the nitrous.
