The ARP intake set is great except for the four end bolts not having studded heads. You need the front two for the coil pack bracket, but I think we can do without the rear two, use the ARP bolts.
Did you buy an intake bolt kit from ARP, if so which one? They are all high dollar, so I went with what I've always wanted, the 12 point SS bolts. The oil pan set I bought cannot work, the pan is too think, so I'll have a lot of spare bolts.
