If you listed the "old rumors and or myths" from Pat Ganahl's book, you'd have another book LOL However, I will see what I can find for documentation

Problem is with port matching to a low riser is you affect your SSR, any rpm range you do that is bad.

I'd wait for KC to chime in, but the power is in the bowl and transition to the seat, that is far more important than port mismatch.

Matter of fact, if I had a set of stock edelbrocks and a low riser intake, and was money limited (not saying he is, but if he was) I would IGNORE the mismatch, and spend my money on the bowl and seat transition, thats where the power is especially at low lift

Basically, I think we sort of agree on "build it for what he wants"

I am not chasing HP either, if he wants a good running street engine just bolt on the low riser intake but dont port

(or, epoxy/weld the intake if he really wants to make things line up, its not tough to do and you only have to go in an inch or so the way the intake floor is shaped)

Then if he wants to improve later, he still has a good set of med riser heads.

Finally, a 428CJ was a great motor, I have had fun in a couple, but if thats the level of power he wants, I'd advise a 390, with a modern cam and headers, it'll run right with it for MUCH cheaper. With a 428 and some work in the bowl, and all the usual upgrades, even with the port mismatch, its way ahead of a CJ league
