Hi Terry,

All may not be lost on the "B" block. The part I stuffed up was the exhaust manifold stud hole but that is subjected to a lot more heat than the head so the threads were practically welded into it over the years. Had to Heli coil it finally.

You may be able to get a few of the thread remains out of the block with a dental pick if they are not as badly siezed as my manifold stud threads were. You then may be able to get a tap started squarely to finish off the clearing of what little threads still remain in the tapped block.

Hope all goes well.

Cheers,
