i got an engine from a truck and when i went to take the heads off 3 of the bolts are rounded..... how can i get them out?
thanks

Weld a nut right on the top of the rounded bolt should come right out. Has work for me several times.

Either the welding trick or you have to drill the head off the bold.

Use a round socket http://www.nastyz28.com/ubb/wink.gif
