Try this. Remove the thermostat housing and thermostat. This is where your going to fill your system. If your radiator petcock isn't located at the high point of your radiator attach a piece of hosing to it and raise it above your radiator. Open the petcock and until coolent flows nicely. Close the petcock and fill your system while holding the radiator hose end level with the thermostat opening in the block until the system is filled and the coolent runs from both the block and hose. Re-install the thermostat and housing and quickly re-attach the radiator hose. Run it until it get up to operating temp and the thermostat is open. Blip the throttle a few times to get any trapped air to move to the top of the engine. Let it completely cool down ( the next day) pull the thermo housing and check the level for any trapped air. re-fill as necessary. You might also want to install a thermostat housing that has a tapped hole for a temp sensor. Chevy used them. You can install a short piece pf pipe in it that becomes the high point of the system and with some pipe fittings attach a petcock on top of the engine which will become your bleed point.
