B (383) and RB (440) intake manifolds and HP B/E Body exhaust manifolds

Need unmodified:
1x 383 B non-high rise aluminum intake manifold in either 4BBL or 2x4BBL.
1x 440 RB non-high rise aluminum intake manifold in either 4BBL or 2x4BBL. Found!
1x pair 1968-1969 HP B Body exhaust manifolds without cracks - dirt, surface rust and broken flapper is fine. Found!
1x pair 1970-1971 HP E/B Body exhaust manifolds without cracks - dirt, surface rust and broken flapper is fine. Found!

Would consider 1968-1971 cast iron intake manifolds at reasonable price, not looking for rare year matching. I have EGR B and RB manifolds.

2806301 intake 383 4 barrel engines from 1968 through 1969 Found!
2951666 intake 383's in 1970 and 1971
2951736 intake 440's in 1970
3512501 intake 440's in 1971 Found!

Putting together two mild big block engines this year and looking for single four barrel or short dual quad intakes, not tunnel rams. Using my rebuilt Carter AFB/AVS carbs on them. Also want to get two sets of HP big block exhaust manifolds. Would prefer 68-69 B body set and a 70 E body set of HP exhaust manifolds but will go with higher quality headers if I need to pay reproduction exhaust manifold prices for used original.
