B screw in backwards

I have one hill that kicks my a55.
I have 50/34 crank., 10 speed 11 x 36 cassette.
Can see an 11x 40 in my future.
Chain length ok?
I took out 3 links ( actually 4 links and added a Quick-Link) because I was getting a lot of sag in the 34-11. There is enough room between the jockey wheels in the 50-40 ( with the B screw reversed) but it's about one link to short to go in there easily, not that anyone would use either combination except by accident. It goes into the 34-40 very easily. Wolf Tooth sells a longer B screw for about $3.00, but someone on another website or U-Tube video said that long screw pushes past the short cog it engages, it's just a small cog and the head on the reversed screw is much wider and engages very well. Looks like that to me too. I don't know how many links are in a new 105 chain.
