Just throwin this out there... Has anyone heard if it is possible to port the apv, viv, ssv valves in the intake manifold? Im takin mine apart soon to clean it cuz my ssv or apv valve is stickin and i havent looked at them closely yet but from what i saw quickly it looks like it mite be possible. Just wonderin if it is or if theyre pretty much as big as they get already or what. Let me know what ya think, thanks!

 

You can clean some casting marks off of them but there's not much more else that can be done.
