Thanks for the information everyone.

Bobby, if you didn't already know the main reason they go to 5.3 heads is to raise the compression to 10.8:1 on the 346 motor, considering that they flow almost identically with the same size valves. I didn't realize that they mounted dirrerenty on the intake, why would this cause a problem? Or would it?
