Im fitting new pistons and getting my head reworked,at the same time i want to fit new ARP rod bolts and head studs.Im just alittle confused with what i need for the head as some ARP kits say head bolts and some say head studs.Which do i need for doing the complete job. Is there a ARP kit that has all studs /nuts needed to refit the head?I live in the UK and so want to make sure i buy the correct kit ,as sending it back to the USA will be expensive.
