Reply to "Carburetors with Annular Boosters"

Very interesting your link and once again I regret not to read English more easily.

I found a supplier for a "Pantera" Blue Thunder intake manifold. he offers me to choose between two models, the "normal" and the "competition", the difference lies in the fact that the "competition" has a "Cut-down center divider for more high power RPM & no heat riser".

For a 450hp street engine with a 750 cfm Holley 9379 what do you recommend? I thought of something in between, without the heat riser but with a normal center divider?
