I am replacing the plastic intake with another plastic intake, but with alum. x-over. Are the gaskets that go between the head and intake reusable? I thought they were the o-ring type. I have done a Cobra intake, and know those are reusable. I am not as familiar with the 2v intakes. I would like to know before I take it apart, so I can have all the right parts I need. Late night parts store runs really suck, and 4.6 parts are next to impossible to get in my area. Took a week to get a t/b and IAC gasket for my 2v. Thanks.
