Okay, although "basically the same" as the later distributor, you '62 distributor is slightly different.

Read the assembly instruction #6. You install a new pin through the distributor shaft and gear.......THEN you "stake" the "pin hole" to keep the pin from vibrating out. You don't stake the gear on, you stake the pin to retain it.
So just spread it apart much as can that work! That glop on sides of gear dont make sense you dont pit that back on?
You are slightly deforming the edge of the pin hole, after the pin is installed, not the gear teeth. A center punch and small hammer are all that you need.
Ya got new gear guess says have drill out hole larger to fit roll pin,even shaft as well so how to assure its straight? Any ya all done this? 394 restore fun stuff!

Hey olds fans just got new distributor gear says have to enlarge hole to fit roll pin anybody done this? Seems have to make sure drill straight? Thx heres some pix thx!
My Hosier translation: "Do you fine sirs have any recommendations on how to ensure I drill the gear and shaft of the distributor straight for the too-large pin that was provided for my 394 restoration?"
My counter-question to the OP is, why not try a pin of the proper size and avoid drilling anything?

Why would that be done ? Are they not drilled through the center of the gear and the shaft ?
The gear isn't perfectly symmetrical as it relates to tooth position and pin location, the ignition timing can still be set if the gear is 180° out but the distributor clock position will be off. This could cause the vacuum advance to hit something e.g., the firewall or intake on some applications. I've read but never measured that 180° out = 14° of timing.
The split roll pin that the "Olds Parts Guy " sold you is the cheap and easy way out! Those pins fail over time as they have no cushioning ability from the shock/strain loads put on the gear from the oil pump! What is the actual size of the hole in your gear and distributor? The later 330 to 455's use a 1/8" by 7/8" long coiled spring pin. May be the same for yours.
Heavy Duty Coiled Spring Pins
End ViewFor tough jobs, these spiral pins are 30% stronger than our standard coiled spring pins. They remain flexible after installation to absorb shock and vibration, and work well in holes that are out of round. Use them for fastening, pivoting, and holding.
Squeeze pins closed and install them in a hole. Tension holds them tight against the hole wall. The chamfered ends aid insertion.
Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
All pins meet ASME specifications for material and dimensions. Metric pins also meet ISO 8748 specifications.
Steel pins offer good strength.
18-8 stainless steel pins resist corrosion better than 420 stainless steel pins. They may be mildly magnetic.
420 stainless steel pins resist wear as well as corrosion. They are magnetic. Those that are passivated offer added protection against corrosion and oxidation
