Upgrading to studs can allow for easier install and removal of your exhaust manifold. All studs feature a bullet nose radius on the ends to help locate the pan rail holes, this also allows the nuts to be easily installed without the risk of cross threading.\u003c\/p\u003e\n\u003cp\u003eThese Aeroflow header studs are made from chrome moly 8740 material for high strength properties.
