OK, FWIW, here's a dyno test performed by Grassroots Motorsports (April 2001) 
on an Dual SU 1973 MGB engine (which seems pretty similar induction-wise) 
under well-controlled conditions. The summary is as follows:

Orig engine baseline       56.8 bhp
Add Pertronix ignitor       61.1 bhp      +4.3 hp       +7.6%
Add Ignitor & MSD 6A     62.7 bhp     +5.9 hp       +10.4%
Optimize Timing             64.3 bhp      +8.5 hp       +13.2%
Add K&N air filters          65.9 bhp      +9.1 hp      +16.0%

The K&N's alone added 1.6 hp. They found that the paper element 
"pancake-style" w/chrome platter type housing was the best choice. No filters 
at all gave a 2 hp increase.
