Crosswind vs. RPM Intake

I will say I like the crosswinds dual bolt pattern, not sure why edelbrock wouldn't add this other than for the fact if you switch heads you'd also have to buy another one of their intakes.

I was considering a crosswinds for the engine I'm building, it's a magnum block that will have magnum eddy heads (which don't offer the LA intake bolt pattern) and I want to retain the LA timing cover and water pump.
