Poncho, from my experience with my bird, your advise is dead on. I've been through each and every one of those steps myself and I now have finally beaten the running hot syndrome. I am running a two core alluminum rad, 19" 7 blade clutch fan, ALL baffles/fillers, 190 thermostat, and one bottle of Royal Purple watter wetter type product. And finallly have the timing set correctly for the new roller cam. All in all, I am now running 190 max. Even the other day when it was darn near 90 I let the car sit and idle and it didn't even hit 180. All of this after 8 years of running hot every season!
