When we tryed to get the aftermarket heads leagal for the Mopar BB , we first got the Mopar performance 452-A heads leagal for SS onley. At that time their was no way that the Edlebrock could be legal for Stock/ SS, because off onley one thing, their was angel spark plugs. Bruce told us now way ! Then after a year or so Edelbrock came with a straight plug style, and it was ok.
But that was a Mopar, not a Chevy !.
