Default Weber velocity stack length

I did remove the phenolic spacer in order to get better hood clearance, but definitely the carbs were getting much hotter, so I had to put them back on.
Unfortunately the screen filter I have on the normal 2 1/2" stacks touch the bonet, and I have had one of them knocked of and lost it. The rocking engine keeps hitting the stack with the filter against the edge of the cutout for the scoop.
I have checked in Cobra Restores for a special wider scoop for Weber equipped Cobras, but they do not offer it any more. I am also concerned that the wider scoop will just not look right.
I wonder if shorter 1 1/2" stacks will work properly or if they will affect performance much.
Of course the auxiliary venturi would have to be milled off to the correct height and the upper radius be machined again.
Any experience or suggestion to this problem?
