400sbc steam hole pics

i would like to have a picture of a 400 sbc with where the steam holes are (there's a bunch and i'm not sure which they are)

i have a 817 block if that makes any difference.

thanks

The two holes closest to the thin part of the block between the cylinders. One on the bottom and one on the top of the thin part. Maybe 1/8" in diameter. Hope this helps
