Peanuts, Big Ovals, and Square Ports, oh my!

[twinturbo427]

I was watching glue dry so I set some big block heads up on the bench for a fashion show comparison.
On the left we have -360 peanut ports, in the middle -781 oval ports, and on the right is an aluminium large square port. Notice the heart shaped combustion chamber on the square ports.

I dug out my 427 block the other day now I guess I gotta dig the heads out. I know they say HI-PER on them, and they are big ovals.
