EFI Vacuum Lines

I know its been posted and asked about a thousand times, but what vacuum lines on an EFI 22R, can be removed. Some tech books ive seen say most of them can be plugged and removed. Others say none

I dont need to stay within emission laws, and am not trying to gain hp.....just trying to clean up the rats nest of vacuum lines and wires on top of the valve cover.

Thanks

im about to do this soon..ill let ya know what i come up with

im in the middle of it. Ive torn everything out, and am just wondering if I need to save it, or toss it.

I wont have it all back together for another few months, so If anyone has some info that would be great.

Perhaps I'll go talk to my local toyota dealership.
