Mercedes W124 2.8 M104 Oil cooler problems. Oil in coolant after sitting for 5 years +

Found this W124 with oil in water after sitting for 5+ years. Tested and changed oil cooler and head gasket to get it on the road, to do it all again because of sticking intake valves. Yes, the old fuel has turned into glue and the intake valves were sticking open when started cold in the mornings.
