Maybe this will help:
Intake heights
Enjoy!
So after an excellent re-snark from Eric, I spent a couple of hours of Google Fu. Was hoping someone with knowledge already knew the answer.
The only thing I could find was this:

Known combos so far...
1. Lightning/Cobra R LWR & Comp Cams UPR.............~11.00"
2. TFS-R.........................................................................11.50"
3. Edelbrock Victor EFI.................................................. 12.00"
4. Lightning/Cobra R LWR & 302 GT40 UPR...................10.50"
The other thread here showed the Lightning at 10.6" and the 351truck lower>BC adapter>5.0 upper at 10". So it looks like the BC adapter set up is still the lowest, but doesn't necessarily flow the best.
