I have read everyones posts and one things stands out as an un-answered question. Yes you broke 2 bolts and you have several options on getting them out but, why did they break! I don't know what size bolts hold the mains down in a 292 but I'll guess 7/16, these shouldn't have snaped at 100 foot pounds of torque period. The torque value on the main caps is based on main cap deformation not the max torque value of the fastener. Even if you did torque the bolts to 95 if they were healthy bolts they should have perhaps deformed the cap and tied up the crank but not break. The only way a bolt that size is giong to break at that value is if it bottomed out or was not up to par in the first place
