Sealants are unnnecessary and even ill-advised on the intake/exhaust
manifolds. However, it is mandatory that the manifold surfaces and
seating surface on the head be very clean and flat. If they are not,
sealants won't do you any good. The big problem is temperature--even
the red permatex won't stand up to exhaust temperatures, especially
given the pressure.
