Using S13 Swirl Valve on an S14 Motor w/S13 Intake Manifold

I’ve just put in a S14 motor in my S13. I’m going to use the S13 intake manifold but I noticed that on the S13 motor there was a swirl valve/pipes/hoses that the S14 motor doesn’t even have the treads on the back on the motor for the solenoid and stuff to bolt on. What should I do in this case? Just hook everything up from the S13 intake to the solenoid/hoses and just leave it hanging on the back of the motor? Or should I use the upper intake from the S14 so I can delete it and use the lower part from the S13 intake?

Here’s a picture of what I’m talking about.

Thanks for the help guys!
