How do I remove the head bolts????
 

I am ready to take the heads off the car. Took the cam shafts off. Now there are 8 head bolts with star shape. What type of tool do I need to take the bolts off and do I need to do in sequence?
Thanks

its a 12 point socket. I forgot the size. 14 mm I think.. start with the outer most bolts one on each side then work your way towards the middle...you will need a breaker bar or long ratchet they are very very tight.
