ARP Head studs are a good idea... torque with ARP lube or moly lube. It comes with the kit... Dont get my comment wrong bout OEM head gaskets. You wont blow one out any easier than a fel pro. The reason I dont like them is because they only have a very very thin viton covering on the gasket and will seep oil alot easier than fel pro gaskets which have a thicker and more tacky coating. If you ever notice you will find alot 4.6 Mustangs (especially 2 valve) will leak oil into the valley pan (area under the intake manifold) they will also have alot of dust accumulated on the sides of the block. This is becase oil of oil seepage between the head and the block. Ford recalled alot of them. I have pulled motors down that were leaking pretty bad, cleanen the decks with brake cleaner and threw them back together with fel pros and they never leak again... If I do use OEM MLS gaskets I spray them with copper coat which provides much better sealing against oil seepage. You just have to be careful and spray to 2 or 3 light even coats. I actually do that on alot of head gasket even on pushrod motors and have always had good results.
