I swear that the head on the 4g63 motor is bolted on to the block with bolts! I bought a set of ARP head bolts form Gruppe S, and they sent me a head stud kit. Some one, please tell me that I am correct and they are suppose to be bolts and not studs.

 

same difference...


alittle quote:


ARP HEAD STUDS
"Recommended for any EVO making over 330awhp. Stock headbolts stretch wich will cause headgasket failures. Install a set of these and you are set."
