I think the factory sheet metal served as a PCV baffle, and also shielded the exhaust-hot EGR passages from a direct soaking of oil. If you end up needing to make a baffle I think it can be much smaller IF using a non-EGR intake manifold.
I dont know what would be the effect of uncovered EGR passages. Maybe it would generate some extra crankcase fumes/smoke? Maybe that would dirty up the carb and intake? I'm sure someone has done it.

Keep in mind the factory metal valley pan was used from DAY 1 of the Gen 2 engine in 1966.....there was no thoughts of EGR then.

Talking about the tin cover riveted to bottom of manifold, not the valley pan.

Pcv baffle was used from day one also. It shields the heat crossover from coking the oil also. It's main purpose is as an air/oil separator.

Rats! tom999q I needed that baffle
Guys get aftermarket manifolds and move over the baffle as directed then sell the baffleless boat anchor to people like me on ebay |

Well I don't think it would be too hard to make a baffle, it was just pressed sheetmetal..
