Performance Intake manifolds C4
Vette Obsessed:
JH, IMO the "best" intake for you would depend on several factors (mainly application & budget in this case).
If you just want to tweak what you have without getting into cams and headwork I would either siamese the intake like Chris has or buy an aftermarket intake/runner combo.
I haven't looked into siamesing too much but I read a while (maybe a year ago when people started experimenting with it) that you had to be careful about how it was done so you didn't get airflow into the wrong cylinder when you didn't want it. Having said that, I imagine that has been sorted out and info on how to do it best would be readily available now.
If you are considering just porting your original intake (rather than siamesing it) I would look very carefully at the cost difference between an aftermarket casting and the amount of labour you might be paying for the porting work.
From memory, if you decide to go with an aftermarket base, figure at least $400US for an aftermarket lower intake and around $300 - 400US for aftermarket "big tube" runners.
From what I have seen, the aftermarket setups definitely have more flow potential than ported stock castings. I don't know how an aftermarket base would compare with a siamesed base though...
Hope this helps.

True, but the aftermarket pieces will flow more air. Depends on what your hp goals are.
