I've had great results with the Merc water pressure relief valve.
Here's a thread on it.

is there any way to install a ballvalve to lower water pressure. i know trimming the pickup works better can also let u pickup more speed. was just wondering if it works i put some on my innercoolers but havent tested them yet.

A ball valve doesn't control pressure, it limits volume.
I installed the Merc relief valves on both of my completely stock motors after seeing over 35psi at cruise speeds. After screwing around for the better part of the summer trying different dumps, valves, different t-stat housings, I bite the bullet and installed the Merc valves. Now all is perfect!
