The Gen 3 h/g has different water passage to gen 2 h/g
You might wanna check that out first.

yeah it's slightly different, but the difference is very little, there is still similar amounts of coolant flow into each coolant jacket in the head, just a little less on the intake side

Yeap, there are speculations if Toyota did this to force more water to the exhaust side, and cool the valves / block / whatever to reduce the "detonation on #3" problem that many believes.

Let me know if it works, because my h/g is blown (Thanks A1 turbos!) and looking into getting something a tad stronger.
