Is the "angle channel" #24.... right? If so, they are the same size on both blocks.

and some blocks have a horizontal connection. You can still call it an angle channel. The horizontal channel reduces sloshing and doesn't need a siphon break.

As well as the high or low hole were the IFR is NOT pressed in.
The IFR (pressed in brass insert) in the high/top is .061" esh the lower or bottom (3310) is .054" esh.
Is this right? do they need to be a larger size when there in the top compared to bottom..........or should the size be the same top or bottom.....?

No. too large.
