same problema as last week or did you burn through a piston crown? With the timing advanced, did you have any audible knock? It sounds to me like you are experiencing pre-ignition. Not detonation, pre-ignition. The biggest difference between the two is that severe knock over a period of time can cause major issues.
ONE event of pre-ignition will silently detonate your motor.
Here's a link to a great write up on the two:
