Ron, when I built mine I moved the shaft over .100" also. I kept the Donovan Chrysler adjuster ball directly over the center of the push rod hole and used Isky roller tips with their pins and keepers. I used a stock shaft centerless ground down .002" to fit 2 narrow roller bearings I bought from King bearing at the time.(gap in the center for oiling) I was trying for a 1.7 ratio but ended up 1.63 ratio measuring the valve lift to the cam lift.
Yours must be farther off-set since you elongated the push rod holes.
I have a 2 sets of original NOS Thomas Hi-Lift magnesium rockers I've never used. They are just shorter on the short side and would need to have the holes larger if using larger diameter push rods. I believe they were intended to use the stock push rods and were probably OK for a stocker looking for a little bit extra power. Some day I'll put them to good use. Right now I'm keeping them from the hoarders.:)....Good Luck JD
