Should I replace the stock 360 intake?

Originally, when the Little Red Expresses were being advertised, they were slated to come out with the W2 heads. I remember reading some info on that sometime ago. I don't remember if it was cost, emissions, or why it never made it to the table. Anyone on here have the real story?

The story goes that 2 W2 engines left Detroit in vehicles one went to Ron Hall? and the engine got pulled and put in an A body? The other was running around Michigan for awhile.
There were 2 440 Little Reds built that went to Canada and there were Little Reds built in 1980 and sent to Canada also.
