I know this has already been posted, and i did a search on it, but all the replies on that thread didnt make since, because people were arguing. OK here is the question, and i would like a response from someone who really knows, I have a d16z6 bottom end, but im using a d16y8 head (this motor is built from "ground" up) I have d16z6 head studs from ARP, are these the ones i need? or do i need d16y8 head studs? PLease be helpful with this, my built motor is almost done, except for this small thing. Thanks guys in advance!
