Note:  There is one modification needed in order to use that above kit and that is to install ‘heli coils’ or ‘timeserts’  to change the thread for the head studs. Those studs are prone to pull out with the stock thread size and we require that a 3/8 – 16 thread gets installed in order to use the ARP head stud. This service is available from cNw of course if you don’t have a local shop that can do this modification
