Yes the low decks don't have the best selection of dual quad intakes. Basically your choices are a OEM early 60's cast iron dual quad intake or the dual quad offy. Neither look like there were designed for flow. At least the CH-28 intake for the 440 will flow decent, but the low deck version of the performer RPM intake or holley street dominator would blow either of those low deck dual quad intakes right out of the water.
