I haven’t had a chance to take them in. Clocking 108 hours this past week at work...taking next week off. I’ll take the rods in then. The good news is I marked each rod and made sure I marked the front, that way I know where they were to begin with.
They have a thrust face that faces the rod next to it. It's the larger flat side/face of the big end of the rod.
You can mix n match then as long as they all have their thrust facing each other and keep the numbers facing out/oil holes towards opposite bank.
