Break in gone bad... 360
Not enough timing will make them HOT.
When breaking them in, I always suggest get it up to rpm quickly and then time it right away to 36-40* BTDC.
Once you get the heat monster going, especially on break in, it's hard to get it back under control.
I also always check new themostats in a pot of water to make sure it opens.
Hope things aren't hurt.
