I snapped a head bolt off, leaving about .25 in. on the block (1986 22R). The only ways I can think to remove the rest of the bolt are: A) torch the block and use vise grips to twist bolt; B) weld a hunk of steel onto the bolt and use vise grips to twist bolt (meaning I have to get a welder--will oxy-acetylene work?); C) drill out bolt and use an easy-outer to twist bolt(which has NEVER worked for me and I've even snapped the easy-outer into the bolt!). Advice on the above or other suggestions? Thx, RustNSs
