Knock yourself out.

Timing too high. Adjust timing chain lash or replace automatic advance actuator. oh don't have OHCs huh?
Running too lean. Take those damn K&N filters off unless you are going to compensate with bigger jets.
Running dry N2O? Hey if you are going to spray N2O you need to retard the timing a bit and put some hot plugs in. yeah and stop using regular gas.

"Running too lean."

Ah, but WHY does running too lean lead to detonation?
