PCV and vac. lines, where does it go?????

I think I typed the wrong wording. The Edelbrock guy told me that the heads have pocket grooves manufactured in the head to prevent stem pockets from forming. I should call him back though just to verify. He said that the only cooling issue with the Edelbrock heads is gaskets being installed incorrectly. I also should call TF and ask them if any other heads would require the block to be machined.
Regarding the ECT sensor. I have mine placed in my thermostat housing, is that a problem? I think the stock 5.0 has it placed in the manifold rather than the thermo. housing? Maybe since I placed the sensor in the housing it's preventing the thermostat from opening completely which in turn restricts my water flow?
And yes, a little LCD light would be nice.
