Engine Bolt Torque Chart Engine bolt torque specifications 426 hemi, rb, b, la engines. these specs are for stock type bolts with light engine oil applied to the threads and the underside of the bolt head. moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. if you use aftermarket performance bolts like arp’s. This repairengineering bolt torque chart was created assuming a value at the mid point of that range at 75% of the material proof strength. bolt proof load is defined as the maximum force that the material can support without experiencing permanent deformation. although material properties vary, an approximate estimate of proof strength is. Use hardened steel washers when installing aluminum cylinder heads. this will prevent galling of the soft aluminum. check the accuracy of your torque wrench and recalibrate, if necessary, before bolting down your cylinder heads. and finally, follow these torque sequences for your engine: source: fel pro. graphic by: lori sams. Gen 3 hemi torque specs. the torque specs are fairly similar between the gen 3 hemi engines. however, there are some differences. please see the chart below for some of the critical torque specs for your engine. starting with the center main cap and working your way out, tighten each m12 bolt ;to 20 ft. lbs. once that is done, repeat the same.
