Stay away from the moly and/or Teflon based thread "sealers" on the market. They can wash away when exposed to the environment of an engine's internals.
A nice sticky Permatex gasket goop will work great and stay put.

No evil in that. Don't get hung up on the non-friction aspect of the Teflon ingredient among many others. It's appropriate in both the Permatex and ARP formulas because of its non-reactive properties in corrosive chemical environments. Like what happens to oil in the presence of crankcase / exhaust gases...
ARP 100-9904 Sealant Thread Sealer is also Teflon-inclusive. And this guy has no problems with it over the last 14 years.

Seriously guys, this has been discussed over and over.
Permatex Indian Head used to be the sealer of choice but High Tack is better. It's impervious to oils, fuels, coolants and temperature cycles. Years down the road, pull the head bolts/studs and High Tack is still coating the threads.
