These are the crucial bolts that clamp the cylinder head down onto your engine block, creating the seal for your head gasket. Factory head bolts on the big 4.8L are 'torque-to-yield', which is a fancy way of saying they are designed to stretch when torqued to spec. This makes them a one-time-use item, plain and simple. Re-using old, stretched bolts is a recipe for disaster. They won't provide the right clamping force, leading to a freshly replaced head gasket failing in no time. Don't risk having to do the whole job twice; it's a massive, expensive headache you don't need.
When ever a head comes off, it is always recommended to put a new set of head bolts on during installation.
