Proposed a filter, carb setup

I did look for a spread bore intake.
Limited opinions

Speed master spread bore only good
To 5500
Edelbrock, if I remember, Sticker shock

A friend of mine is a great aluminum welder,

I'm thinking a used Speed Master Chinese Edelbrock knock off
That he modifies for spread bore

at this point I can't get the hood closed with the air filter housing, TQ adapter, nitrous plate, gaskets

No, I'm not ready to cut the hood yet

Will it clear with just the nitrous plate and a thin square bore gasket between the manifold and plate and a thin spread bore gasket between the plate and carb?
If it does see if there is enough room to put the spread bore bolt pattern in the top of the nitrous plate so you could drill and tap for studs or bolts to attach the carb.
Check to see if the nitrous plate has room to countersink socket head screws so they are below the top of the gasket surface of the nos plate.
If all that is doable then you would need to blend the shape of the spread bore into the top of the nos plate to the square flange at the bottom with a diegrinder. Making your nos plate into a spread bore to square flange adapter.
Good luck.
