Oh yeah,
Lifter holes & oil galleys are atrocious and will need much deburring
Head dowels are too close together, plan on grinding dowels to fit heads
Check threads on every hole, pipe threads will need to be tapped deeper
Grind relief in the valley where inside head nuts go for wrench clearance if it's a Hemi
#7 exhaust pushrod might need more clearance if it's a Hemi
All the .246" dowel pin holes were way too tight
Ream dowel holes to .245”
If it's a Hemi and you are going to run TTI headers, if you wait to grind for clearance on the block until you get it in the car, I'll go ahead and offer $500 for your car now. And at midnight the night you put it in you will call me to tell me to come and get it.
There might have been more, but that's all I can think of.

I did a video on Callies block prep. If you want to see it, I will look up what number it was.
