Decisions Decisions Decisions....
It appears that you wallowed the bolt holes on some LA intake gaskets to do this experiment
I just got done flowing some intakes I had around the shop. I have done it before, but I could not sleep last night so I go busy in the shop at 2am. These are all SBM intakes
Here is what I found. All flow numbers are average as inner and outer runners flow different.
Mopar M1 Gasket matched 288cfm
Edelbrock Victor 340 out of the box 254cfm
Indy Single plane W5/360-1 some porting 375cfm
Mopar W2 Single plane gasket match 296cfm
Edelbrock Super Victor Gasket matched 331cfm
Crosswind out of the box 225cfm
Crosswind Gasket matched 257cfm
Edelbrock RPM out of the box 242cfm
Weiand Stealth Gasket matched 272cfm
Take these as they are. The flow may not be exact to some other shops bench, but they were all done on the same bench and that will at least show the flow difference between the intakes. Enjoy .
Thank MRL... If you have an Pro Products, use it. Ran both,the LA Eddy Air Gap shows an advantage.
(On bigger than stock Magnum based heads.) Both work, one can work better in certain situations.
