"One test is worth a thousand expert opinions."
Your intake manifold needs to have the rear ports to connect to. I have added them in the past to intakes without them.
You can drill & tap for AN fittings (not easy, need milling machine) or you can weld on bungs.
The rear cylinders run hotter and this is supposed to make the temperatures more equal.
Think about it, the cool water is pumped at the lower front of the block and gets hotter and hotter, rising up around the cylinders as it gets to the rear. Then it has to find its way all the way back to exit at the thermostat mounting. This kit lets that hot water exit at the rear.
If you really want to do this, get an intake with the 4 bungs, run hoses to connect each front & rear together, and use the inline t-stat mount. That should be the simplest way to get this done.
