Ever since I started using a Lisle radiator funnel to fill my engine(s) whilst they're able to run, so they can burp themselves, i've never had any air pocket issues again, with plugged rear coolant holes, plugged bypass + 3x holes in t/stat. Before, I always had trapped air problems and for the first 3-4 heat cycles i'd run the engine and the eng temp gauge would fluctuate a fair bit until the air worked itself out. Now I just fill, warm up, let cool down, cap on, top up overflow then it's good to go.
