PN is 12498545. FYI, they are torque-to-yeild one use only. Cant reuse them after theyve been tightened. They can handle over 500hp but make sure you blow out the bolt hole with air or vacuum because if you leave some water or oil that is incompressible in the hole you can crack your block when you tighten the bolts.

im on GMpartsdirct.com and im able to find the parts i need but i cant seem to find a way how to get the part number of it, so i can order it at the local GM dealer....

no that Pn number is correct, im trying to find other parts besides the head bolts, for example head gaskets for the left and right side, i find the gaskets, but cant seem to fint the PN on it... even shows me an illustration of the side of the engine where the gasket goes....

Head gasket for 5.7L PN 12573949 and 12558809-10, dont why different numbers but probably different materials. Both sides might be same gasket shape. Just in case, valve cover gasket PN 12561912
