This is the last bolt I need to get out... 440 #2 cylinder. Hooker Super Comps. Tried a crow foot but the head is starting to strip. I do not have a torch. Would rather not destroy it/looking for a clean removal. So far I have tried (1) sliding the header forward (2) Needle nose Vise grips and a crescent wrench, (3)Crow foot, (4) Praying to higher powers including the Blessed Mother of Rapid Acceleration. Suggestions welcome other than dynamite (Had a bad experience with that)
