Sounds like there's something generating heat, or the cooling jacket's crudded up. The block should be airless shotted, it blasts the crud off the cores, and boucnes all thru it, so everything gets cleaned. What oil pump are you running, and what pressure does it maintain? The latest 422 I did, even at 9.8:1 and +.060 overbore, runs cold with a similar setup. Only hits 180 on long light throttle hills in 90-895° heat. Good efficient engines dont run hot. And I think it's more than timing or fuel.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
