Should I replace the stock 360 intake?

Sounds like I should stick with the original intake.

I have not got the suggested specs. from the builder yet, but I told him I want a fairly stock engine, he will order a new camshaft as the old one had a few lobes that was a bit rounded.

Here are some pictures from the disassembly, parts seeing daylight for the first time in 41 years:
