So the glows do do a flash, fair enough, im sure you will get them glows out , folk say get the engine hot and try but i found with the vauxhalls with the fiat engine there a bassa for snapping in the head , i found a stone cold engine was better for getting them out , its just 'feel' thing and work them back and to if they start to fire up in the thread coming out .
You have taken heads off it , sure you will do the glows no worrys
