I removed one of the head bolts when I was dissasembling my engine, to suck the coolant out of the block (I'm tired of it dribbling out of the holes as I pull the bolts out). I thought I blew another head gasket, but it appears to be intake manifold gasket instead. So when I put the head bolt back in do I need to loosen the rest on that head and retorque them all in order, or can I just torque the one to spec?
