Diego! How are ya bud.
I gotta ask, you stroked your 318 cubic inch engine to a 360 cubic inch engine?
Is there any port work done to the heads?
On intake compare's. Theres only a little difference between intakes between dual planes and single planes. Alot of what intake would fit best depends on what your doing with the car as well as the cars gear ratio and stall speed on the trannys converter, like Moper said.
You have enuff cam to run a single plane, but if your stall converter and/or your gearing is low, the dual plane would be the way to go.
