Jim, I have never used a SV for a BBM, so I really can’t answer that.

However, a 572 I built that used 572-13 365 heads and the 3x intake made peak tq at 5600.
That manifold was just port matched to the heads.
Those heads have ports with a larger cross section and bigger valves than some EZ325’s, so I have to believe at least some of the higher peak tq rpm is attributed to that.
