MKII SQ4 IMD pistons to Club con-rods

What is the best method of getting the correct clearance of the IMD piston gudgeon pins to the Club con-rod small ends, reaming or honing?
If reaming is satisfactory can I do it by hand, if it's honing, it's off to the machine shop again.
Can anyone advise me?
Cheers, Dave
