Sweetie, sweetie, calm down. If you post crap, expect it to be pointed
out as such. You're starting to 'project' a lot, you know.

Smaller valve mass on a 16 valve head maybe, but still.

Oh yes, but the point remains. More revs = stronger springs needed.

Already been done. There's even a well-known movie scene about the
episode.
Dr. Frederick Frankenstein: [to Igor] Now that brain that you gave me.
Was it Hans Delbruck's?
Igor: [pause, then] No.
Dr. Frederick Frankenstein: Ah! Very good. Would you mind telling me
whose brain I DID put in?
Igor: Then you won't be angry?
Dr. Frederick Frankenstein: I will NOT be angry.
Igor: Abby Someone.
Dr. Frederick Frankenstein: [pause, then] Abby Someone. Abby who?
Igor: Abby Normal.
Dr. Frederick Frankenstein: [pause, then] Abby Normal?
Igor: I'm almost sure that was the name.
The point being -in both cases: you can't harvest something that isn't
there.
