71 Dart get 408/ Trick Flow Heads....

I just placed the intake gaskets on my 96 dakota sport that has the trickfkow heads. I noticed the oil drain holes weren't very big. I am not doing it now. But was wondering if it wouldn't hurt to have the holes made bigger, the next time I have the heads off?
I have wondered about this also. The supply is much smaller than factory also. Which may be a needed improvement as some guys will restrict oil up top anyhow.
