So I stripped the head bolts complete out of my old motor I have tried everything I can think of to get them off how do I get them off even with good head bolts Scion said it calls for 12mm 12pt star socket any suggestions

 

stripped as in you rounded the head of one of the bolts off? Did you take some out and leave some in?

 

no if you look at the top of the bolts the inside is stripped
