Bolt - OE TTY Cylinder Head Bolt Set of 17

Any time a cylinder head is removed and gaskets replaced these bolts must be replaced, they are not re-usable. These are torque to yield bolts meaning they stretch to hold even torque when installed and will not do the same if re-used. Failure to replace these bolts will certainly cause another head gasket failure and leaks internally into the engine as a special sealant is applied to the threads of new bolts that is absolutely necessary and regular paste sealants will not do the trick. These fit 6.2 and 6.5 engines and are original equipment as was found in the engine from its manufacturer, sold in sets of 17 (enough for one head).
