Pick An Intake

Want to put a 4-bbl on my '71 Dart GT with a 318, auto., 3.23:1 SG, elec. ign., and 2 1/4" duals to FlowMaster 40s.
I've located two intake manifolds:
1. Is a 1970 340 manifold for $30
2. Is a 1974 360 manifold also for $30
Which would you choose? Will either one work with my stock 318 heads?
Any other options/opinions?

Thanks,

Dan
