Were all factory head bolts "sps"

Have a motor that has kxv on them. Are they replacements? Has this engine been opened?

RC said that factory head bolts off the assembly line were "SPS" and the long bolts would have a "C".... Most recent are "KXV" and showed up around 1991 so seems you motor has been opened at least once

Thanks Clint. I was told this was a replacement motor. It is a 109 but not a sg1.
