I know from some old ported iron heads that putting in a bigger intake valve "just because" won't necessarily make much difference. But for something like an Indy SR or EZ (or a regular Victor for that matter), when would it make sense to switch from the standard 2.19 to a 2.25 intake? Would it be based on cam lift, or how much porting the head has or what other things would determine if it is a good move?
