I've seen it done both ways and have heard it is a bit tricky putting the exhaust manifold and intake back on when the head is in the car. Also is just a standard head gasket from one of the parts stores adequate?

Tried this out last night real quick since it is a simple test. I used my drill press with a scrap piece of poly to make a flow restrictor. Didn't make any difference.

I use restrictors on my street driven Wagon as well as wife's car but it needs one a Fox body Mustang with a 572ci. BBC electric water pump also street driven by her. They make full sets of these plates so you adj. the size that you need for the app (One Size Does not Fit All).

That said if the amount of time needed to stay in the radiator meant nothing and only flow accounted for cooling why have a radiator? In a stock 4.0 a thermostat is required as it is in most all modern cars for the computer to work properly. The stock pump/radiator seems to work fine with a cooling sys in good order for most people. If all of those are in good working order I see no reason for aftermarket parts on a stock 4.0.
