B2200 Cylinder Head Torque Specifications Above is the torque sequence for the B2200 cylinder head. Torque should be done in 20 lb/ft. steps until final torque. Torque numbers are below start with bolt one. Bolts 1-10: 59-64 lb/ft. Bolts should never be installed dry, always coat the bolt threads with engine oil, ATF, or high pressure engine assembly lube before installing. The gasket surface of the head must be perfectly clean and as close to mirror finish as possable. Untorque Sequence Bolts should be untorqued in the sequence above in 2 or 3 steps or 1/8th turn on the first step, another 1/4 turn on the second step and then completly loosen. Rocker Assembly Torque Sequence Bolts should be lightly hand tightened in sequence first, then torqued to spec. Bolts 1-10: 13-20 lb/ft. Rocker Assembly Untorque Sequence Bolts should be loosened 1/4 turn in sequence then completly loosened. Additional Notes: Cylinder heads should always be checked for warpage when they are removed or before installing a new head. Less than .003" warpage is acceptable anything more than .003"-.005" warpage and the head should be straightened then shaved. All overhead cam design heads need to be striaghtened before shaving otherwise the cam towers will be out of alignment and you run a high risk of burning up the camshaft. When looking for a machine shop choose one that is racing oriented or a speed shop, these shops should have better equipment, more knowledge, and will care more for getting the job done right. After you finish installing the head and double check everything fire up the engine and let it warm up. Once warmed up (atleast 1/4 on temp gauge) turn off the truck and allow to fully cool. Remove valve cover and retorque the head using your final torque setting in sequence. Not doing this may cause premature head gasket failure within a few months to a year or two.
