edelbrock tech. department told me thier newer heads already are machined to accept spring cups.
How old are your heads? I bought mine 4 years ago.
He didnt say they came with spring cups, just that they were machined to accept spring cups. Apparently, Ford heads have never used spring cups?
Is this just a GM thing?
