Technical Does this Offy 2x4 look different? ?

hey all!!
I have a question, I bought this Offy 2x4 for a 65 401 nailhead and it doesn't look like others ive seen. has someone customized it?? if so, for the better or worse??

 

Yes, someone cut the plenum dividers out of it.

 

There is a lot of info on those intakes out there...........No one seems to think they work well. I never liked the ones I had. A single four performs much better.
Maybe the new mods improved the performance, try it.
