I assume ur speaking of the cams and piston/rods w/ arp 2000 rod bolts. Proof of every part in there we can dissect it if u want. I have extra head gasket, brand new arp head studs, but let me warn u a couple dollars extra if u want miscellaneous parts i have layin around . I was gone reseal(doesn't need it i was gonna do oem TB/oem HG/arp head studs it and listen to my buddy's advice and hit her with a 75 shot. No nitrous or anything been ran through her. Was laid off before i bought slicks and bottle she would've been sick.
