All bolts are reusable. These engines do not use any 'single use' or TTY fasteners. However the factory ignition switch does use single-use shear head bolts.
I was specifically referring to the requirement to resize the rod big ends if replacing the bolts. The bolts are the alignment/placement method for the cap so if the bolts are changed, the rod must be sized for it to work correctly.
Does you engine have the 12-point head bolts? Those can be reused indefinitely as long as they're not stretched from over-tightening.
