The interesting thing about the Brodix head is there is a boss that will allow you to put an injector nozzle behind the intake valve. Not that we would do that because we like the air/fuel mixture in the intake runner. NOS guys may take advantage of that boss though.
Or combo is too complicated to repeat for production mainly because of the amount of labor involved in making the manifold (one that works). In making them, the law was that it had to sit low so the blower would not stick out of the hood. I've threaten to take one of our manifold up to Tim Hogan to see if he would be interested in making patterns and a jig.
A bit of meaningless trivia, Tim Hogan got his start in the racing world right out of high school here at Valley Head Service. Over the years we have always maintained a great relationship with him.
