The upper left and lower right were at my parents wedding. The blue impala was my first car ride home from the hospital. Idk what the story on the supersport is, must have been somebody stopping to visit.
And there you have it! There is much more that goes into them that I didn't show in detail here. Port size, shape, bowl size, valve job angles and depths, flowbench testing and port speed, etc. These heads move over 280cfm @ .600" @ 28". Necessary to make 120,130,140+hp depending on the combo.
