Hey I just got my skunk2 intake mani and I was wondering if i needed new tb gasket and intake gasket.

 

Yes you definitely need new gaskets. It's never a good idea to reuse gaskets on anything. You don't want vacuum leaks. You can even get a thermal intake manifold gasket that's made out of nylon or plastic. It decreases heat transfer from the head to the intake manifold which will help lower intake air temps.
