Oh yes, you do feel the difference. The stock manifolds really do restrict flow. It's like the difference between a drinking straw and a fire hose. And they aren't really difficult to install. You need to do it from underneath the van as it can't be done from up top, so you will need to lift the front up.

Hey guys!
This thread was a great help to me, I ended up going the route of the Hedman headers, shorty plugs, and paint for my 1978 G30 Ambulance project.
I noticed a performance increase (judging from the seat of my pants lol).
My favorite part is the sound, Nothing beats a big block withe headers!
Anyway, I filmed the whole thing so if links work here (sorry I am new) you can see how I did it.
Its a 3 part video, I posted the last part here because its the most interesting but the others are out there if you need them
Hope someone finds this helpful!

Great video G30CamperLance - I have a 1991 G10 I just installed these on and the header on the passenger side comes out right in front of the cross member - was wondering if you modified your cross member or if the stock older transmission cross member is just different? thanks

Transmission cross member is definitely different as your van has an overdrive vs the other TH350/400 trans. Post a few pictures so we can potentially suggest a workable solution
