Rb25 Conrod Bearings

[XxNinjaxX]

hey all im currently in the process or reconditioning a rb25, anyway to the point, im replacing the big ends and am just wondering if the number stamped on the intake side of the rods and caps are the bearing grades?

ive been told that i need to look at the front of the crank for the grades for main and bigends are apparently stamped there aswell but ive also been told that the numbers stamped on the rod and cap are the grades

can anyone clear this up for me?

the numbers off the rods are as follows

1# 0/I

2# 0/0

3# 0/0

4# 0/I

5# 0/0

6# 0/I

now those arnt "1"s like i would asume as grades go from 0>2 they look like capital i's but that wouldnt make sense since the grades are numbers only. so should just asume they are 1's?

all feedback welcome
