Follow up on leaking head studs

We talked with ARP, the stud manufacturer, and they stated that the issue we had was that the PTFE compound was cracked loose when we torqued the heads.

They recommend that the head is installed and torqued immediately after installation of the studs.

Hello rusted,

It is polytetrafluoroethylene, a long name for teflon tape.
They, (head studs) would get the tratement.

I use the same stuff Dad used in the garage, and on the farm working on our own stuff, Permatex Aviation for studs.
