Take a stock heater flap valve and use a step drill to make you one.
My modified flapper from a four. I used a 1 1/2" hole saw.

Yes, I did that to a new -4 yesterday that was tabbed and welded. IT does seem that the angle for the hose off to the long should be at a slightly different angle, though.
I just bolted up 914-4 flappers to my six heat exchangers 20 years ago and never had a problem. I’m using the same 914-4 flappers today with Bens heat exchangers.
