Carb guys I have a simple question (s)

I have a 1050 dominator I got from a buddy-former member. Anyways it's a 3 circuit & I know I sure the heck don't need the intermediate circuit.
Question is, can I thread & plug the well hole on the body & leave the metering blocks alone ? Since I don't believe there will be a draw from a plugged circuit. But I do need to know where that fuel would enter the carb?
One personal question on if you'd do it, 3 inches of spacer, a 1 inch merge with a 2 inch 4500 to 4150 manifold and should I use the merge above or below the adapter ?
I'm kind of in a situation trying to decide if I should build my 830 into a annular booster 850 of just go 1050. My engine should ingest what a 1050 will suck in
If it's suckin' all that down, it's probably really fun!
