What is the best way to remove these stubborn plugs? John Mummert said he drilled them and then heated with a torch.
I remember one block I spent hours on getting its plugs out. Used heat, broke one allen wrench, drilled, heated, rounded hex, drilled again, heated, and chiseled the bugger when it finally turned.
Also, why do they get so stuck with there being oil on their backside?
