Need help- how do I remove head bolts without cracking them?

My engine has 180k on when it jumped the timing and bent the valves. The new (new to me, but used actually) head is on it's way. I'm down to the head bolts, but I already cracked one (a small crack, hope I am not totally and utterly screwed because of this) either way, I need suggestions for the best method to removing these bolts. I don't have a torch to warm them up, what is the best tool to use (I have the 10mm hexkey on a 1/2 socket with a regular ratcheting socket on top) is there something that attatches to sockets that is like those X shaped tire irons? (something that has handles that would be on either side of the bolt so you can push opposite directions to produce better torque)?

These bolts are really in there. Thanks for the help, Colin.
 
try a breaker bar with a 4 foot pipe over it ...way more leverage.
Careful though, use a 6point socket and not a 12 point or else you run the risk of rounding off the bolt.

However valuable a piece of advice this is, PLEASE!!! Check the date of the original post before you post a response. I'm quite sure the thread starter has gotten these head bolts off by now.

Like stated, look at the date of a post like this before reviving it.

And better yet, research before you reply. First off, the side pull of the ratchet is what cracked the bolt. Adding 4" to it will split the bolt in half. He was looking for a tool that he could apply even pressure to two opposite sides to keep the hex from leaning and cracking the bolt head.

Next, the 1g 6 bolt head bolt has a 10mm inverted hex head and requires an allen wrench type socket to fit the inverted hex.

Finally, the 1g and 2g 7 bolt head bolts are 12pt, not 6 point so it is virtually impossible to use a 6 point socket on either.
