We have been plagued with a close to overheating problem. I can drive to the staging lanes, make the run, drive back to the pit and be at 180 to 200. There have been may proposed fixes for the problem. We decided to go with restricting water from the front two ports on the heads, and pulling water from the rear ports. The rear ports are normally plugged. There is an adapter made to allow you to do this and it bolts onto the stock filler neck. We drilled and taped the back side of the water crossover. I have this adapter, but it would have required us to run the rear water return lines on the outside of the intake. So....

I bought brass hex head female plugs, cut them off even with the heads and drilled 1/2 inch holes in them (equal to the holes in the AN fittings in the rear). We cut slots in them so I can use a large screw driver to both install and remove them.









Now the "hard" part. We could have run braided line between the fittings, and I thought about doing that, I was worried about expansion of an aluminum hard line between the fittings, but it was pointed out to me that the heads are also aluminum and should expand at the same rate. So we made up aluminum hard lines that fit exactly between the fittings.
All lines are finger tight, no stress on any of them or the crossover and the bolt holes for the crossover are centered on the threads for the bolts in the heads.
