Hi!
While assembling my rocker shafts,  I have noticed that the alignment of some rockers are not centered on the rocker arm pads at the valve stem. 
If I double up on the washers between the rocker arm and the stands I can get a much better alignment on these cylinders.
my cam will have around .500 lift. Is this alignment needed or doesnt it matter?
If it is important where can i buy more washers? the shafts are .781" diameter , so 3/4" machine washers are too small and 7/8" are too loose.
Cant find a way to open the thin washers up to .781"
Thanks! Mike
