Anyone know someone on here that has used AN hoses for their coolant lines? Jerry? Pat?

The lower hose in a 16 should work as the after market themo housing I found uses it. But what confuses me is that reducing an existing hose size would be a restriction which would affect pressure and more importantly flow. A lot of the LS guys change out their water pumps to get more flow. Factory rated pressure on mine is 55 gpm. I could install an Edelbrock pump bumping it up to 85 gpm to get my flow back with the restricted new hose size?

I have a feeling I'm over thinking this thing. But I just don't want to install all of this only to pull it all off and junk it later.
