I relocated the telltale to top of the block according to the service bulletin. Recently installed a new water pump, new thermostat. Ran the engine on muffs, after 2 min my temp sender shows 190F so I turn the engine off. I don't have a temp gun but the block really felt hot to the touch, a three count was impossible. Pee stream strong. I took the power head off and everything looked normal so I decided to take the exhaust manifold plate of. Same thing here nothing that made me react, I expected to at least find some kind of blockage.
What is the next step?
