Had a simular combo 383 (around 1991), and it was pretty much a compromise all the way around. My biggest mistake was using the stock torque converter. The cam (pretty much the same 0.050 duration as yours) killed off too much low end torque, and with the stock converter it was slow off the line. Midrange power was good, but not alot of high end power either. I would shift at 5,800-6,000 RPM.
I ran the stock ('71) intake first, and it was decent for the combination. I then used a Weiand Action Plus, and din't notice any real difference over the stock intake. Then I installed a Weiand single plane (maybe a Team G) which only slightly helped the upper RPM range, but made low end torque worse.
Anyhow, changing out intakes on a big block is pretty easy. I'd start off with the stock intake, at least all the stock linkage will work with it.
If you have the funds, get a good hi-stall torque converter (2,800+ RPM) to hide the low end power loss.
