I checked on Mortec and found 3973487 is used on 70-72 350's, and has 75cc chambers. There was no listing for 8978487, so you might want to clean the numbers really good to see if that's what you actually have.

I wasn't able to find that number at mortec, however I did find 3998993. Which is a 75cc head used on 307's and 350's since the early 70's. Perhaps that is the head you have.
Who were the cast called The not yet ready for prime time players?
I think you are referring to "Saturday Night Live". This phrasing was used for a number of years so the list of cast members would be large. Original cast includes: Dan Ackroyd, John Belushi, Gilda Radner, Chevy Chase, Jane Curtin, Garrett Morris, and Laraine Newman. When Chevy Chase left to pursue a film career, Bill Murray "replaced" him.
