I'm looking at building a boosted D16Z6 at this point, and was trying to research everything I need to come up with. I'm trying to find out the part number for ARP main studs and come to find out they aren't in the catalog on ARP's website. I was wondering if anyone knew if there were any that were cross compatible or would I have to go with just stock. I do want to build this right and try to make sure its going to last for a while and just doing the research now, and starting to buy different parts, but do want to try to get those parts knocked out before I dig in to far. Thanks for any responses. -Gary D.
