I Ordered the head stud kit from the parts listed on the main site. Whoever I talked to was very nice and gave me a little bit of a discount when I told them I found the part #'s on 2gnt. Anyhow here is the problem...The middle 6 studs fit fine however they are not quite long enough for the treads of the nut on top to be fully engaged(test fitting with no head gasket installed, so it will be worse with the head gasket in place). So what I am thinking of doing is throwing two small nuts in the bottom of each hole so the stud will sit high enough to engage the nut treads all the way, and allowing the studs to be bottomed out against the nuts. I don't like the idea of the stud not being against something on the bottom of the stud hole in the block, and I really dont like the idea of the nut (that is going to have to hold 20+ psi of boost) only using about half of it's treads. So what do you guys think? If you have done the ARP studs I'd like to know what you did. TIA
