Heat in a coil is also a function of 'dwell'. The less your point gap the more time the coil dwells in saturation mode, heating up from primary coil resistance. If you have a "B" dizzy cam it has a profile that will give more dwell for the same point gap, resulting in more coil heat. Checked your point gap lately? Have a dwell meter?
