Question Taco 007-F5 replacement

I think these are easy questions.
1) I unpacked my Taco 007-F5 and compared it to the 007 that came with my WM. The flange size is the same but the hole opening appears smaller on my new one. Are all Taco 007-F5 the same or are some made with 3/4" openings?
I am installing on a 1" return line. I think it will be ok but just reaching out to the forum to be sure.

2) can I reuse the flanges after I clean them up or should I just buy new ones?
In either case, I plan to use the Durst A1050P Flange gaskets so with those I figure the bottoms of the flanges themselves are not too critical.
thank you.

The openings are not significant. You do need to clean the flanges.

yeah I plan to either run a steel brush on the bottom or a light grind to the bottom.
But there is one thing. I looked at new flanges and there is no groove, just a flat bottom.
Same with the gasket I have, just flat. However, the 007 came with a ring gasket. I have to figure that ring will protrude up. Do you think the flat rubber gasket will cover that ring enough so there is no protrusion and therefore a leak?

The top and bottom of the circ will have a groove for the ring gasket. They won't leak. If you reuse the old flanges just make sure they are clean.

I knew about the groove. but the ring doesnt sit flush with the pump flange bottom. It protrudes a little. but I used a rubber gasket between the flanges and that should take up the small protrusion.

It's supposed to. Otherwise, the rubber gasket wouldn't be compressed, forming a seal.
