In general, advanced timing should not cause cooling issues (though it may cause others). Lean and retarded timing can tend be hot. Same with high compression (if it is not detonating). Should not cause a cooling problem. All of the above to a certain point.

For the pulleys, if you have the thin damper you could probably try a common B/RB 2 or even 4 groove crank pulley as a test. If you have the hemi spec thick damper then it is harder.

With a HV pump that is overdriven at least a little I don't think the pulley ratio or water pump performance in general is the problem unless the pump itself is defective.
