depends on what style rod you have. you should either have press in bolts or what i call cap screws. i guess your saying you have the press in type. i dunno if it is ok to do it like you did it or not. i have the cap screw style rods.
they need to be re sized or atleast checked because changing the bolts can change the clamping load distorting the big end of the rod....you gotta remeber this stuff is invisible to the eye, but can make a big difference in how the bearing wears.....
as for the bolts themselves, it depends on the bolt as mentioned above weather their pressed in or not but all that would be handled by taking the rods and bolts in and having them re sized
