Carb and Intake for 5.2 Magnum

For the intakes the RPM Air Gap is the only one i could find that is advertised as been for Magnums only, the Crosswind states its drilled for both LA and Magnum but not sure with the Speedmaster as it is for LA and later Magnums so not sure what a later Magnum is , the one i have is 93. These are all 1,500 - 6,500 rpm range but i don't know what the standard cam specs are. I am sure any of them would work fine so long as you can fit the vertical bolts, i already have LA headers fitted ,not perfect but line up close enough.
