On the B1 originals is the intake bolt pattern the same as stock. Have a rule that says heads must have a stock intake bolt pattern. Thanks for input

Usually only Mopar racers know the answer to that one The Indy 440-1 have the stock 361 to 440 intake bolt pattern, they flow a hoop more air than a stock 440 head does, a bunch more
