Ive been trying to clean up my engine bay here and there. I have a 305 that came with a qjet setup but switched to an edelbrock. So my 02 sensors basically just act as plugs now? And would it be safe to tie those wires back?

A large majority of it is slung over the back of the motor and goes back into the firewall on the driver's side. If I can eliminate some stuff up front that is not in use, i can probably sling the rest of it over the back of the motor as well, and maybe it would be worth getting a nice set of valve covers.
