I am going to be installing a set of aluminum heads and am wondering if I should use thread locker, tread sealant, or anti-seize on the bolts and studs. I assume a Thread locker on the rocker studs so they don't come loose, and a non hardening sealant on the outer head bolts that go into water passages, and anti seize on the heads under the washer so I don't mess up the aluminum.
