Spark plugs: Autolite 303 for non-resistor, 308 for resistor.

Head gasket failure is almost always between cylinders resulting in two cylinders with little or no compression. Did you examine the bore condition and measure the bore wear before putting the head back on? Oily plug fouling can be from excessive ring wear, sooty black plugs can be from too rich a mixture, sticking choke, wrong plug, degraded ignition, and probably not helped by the lack of a thermostat.
