Those inserts are called "port stuffers" and were initially designed by Joe Lapine of Danbury Competition Engines.
I never saw them used on the intake manifolds before. Just the heads. I am very sure that they are intended to not only be epoxied in but "pinned" as well.

There was some testing done with them in the late '70s as I recall and some numbers showed around a 30hp increase on a dyno.

Funny, I was on the shop from Danbury Competition 42 year ago and they welding pieces of steel into the heads for making a better flow on the oval track.

That time I bought a 1970 Boss 429 ( $12.500) into Kingston by a Ford dealer and ship it over to The Netherlands
