I'll never understand why people insist on spreading total misinformation. Chrysler didn't give a **** and shinola about the "port mismatch" and it didn't make a hill of beans difference. But people are gonna choke, puke and regurgitate the same old WRONG bullshit over and over. It's just that. WRONG.
They've been listening to Uncle Tony types on the internet. the guys with a perfectly good set of heads and an intake but want to take a Harbor freight grinder to them...:)
