Only have generic advice

Heat the manifold bolts up with a torch a few times and then let them cool. Consider using an impact wrench on a really low setting to break them loose.  The banging tends to help free up old bolts as long as you don't have the power all the way up and just snap them in half.

 

Also, if you get one that just won't come out then consider just cutting the head off of it before you graduate to a 3 ft breaker bar.  It is a lot easier to get the remainder out if you decide where it breaks.  An inch or 2 sticking out of block gives you a lot more options than snapped flush with the block.
