If you are really worried about a brass plug blowing out then put a retaining strap across the plug
Agreed, just be carefull not to drill your mini holes for the retainer strap holes all the way thru the core plug bosses. Clean the holes. Permatex #1. brass plugs with deep sides (for more contact area). not sure if there are 2 different "thicknesses" of em like the SB Dorman steel ones I'v e dealt with but just a caveat. Dorman told me that they are selling the thin (steel) ones now. tighten the straps down till they securely contact the plug edges so drive em in just the right amt. Overkill maybe but needed on the stock car
