so some people call them yellow tops, some people call them orange tops. Looks like they come on 5.0/5.8/4.6 and probably a couple other engines '93-2000 ish for the 4 hole nozzle design. If you're looking to buy a set, double check they're 4 hole before you take my word for it.

so I've got most of it together.
You'll only have to extend a couple spots. The PCV hose in the back, plenum support on the passenger side of the engine, and maybe the egr tube. This is where I stopped because I replaced the egr tube, and when I pulled out the old one, it was so caked with oil that I didn't notice I pulled out an extension adapter. So I need to put that back in, you can see my dilemma without it in...

I would have extended the bracket, but the nut holding it was rusted solid and I was actually loosening the exhaust stud.

I'm wanting to see how she runs. Not really sure what PVC your talking about though. Is the egr tube short or something?

PCV valve in the back. the fix for this is to use Gates 18030 hose, then cut to size.

There is no way I'm going to be able to give a good example of how it drives, because holy shit I now have a ton of throttle response! and I assume it's because I fixed the butterflies, the injectors are probably playing a part too. 1 of the old injectors was a replacement and was a white top (160lb/hr), stock is 19lb/hr.

I'll give a temperature review once I drive it awhile

To fix the EGR valve problem, I put the tubing spacer back in, then I had to shave the EGR valves mounting face to angle it.
