Does this just remove air from the rear of the heads or does coolant flow also help to releave a hot spot? If it is just for air removal and you dont want to run all the lines you can just tap the holes in the intake and put bleeders. When you fill the coolant system you then crack these bleeders open to remove air. You will want to do it after running to get any other accumulated air out that may collect there. I did this on my off road buggy and it worked great. It requires a little more effort when you change coolant but eliminates lines.
