on a flat head what type of sealer is best to use on the head studs?? that go in the block

#2 Permatex works for me.
It's non hardening & handles re-torquing well.

I use PTFE stuff - usually ARP:

I also coat the sides of the studs with anti-seize.

#2 Permatex. You can get it at any parts store.

You do not torque the studs, just run them down until the shoulder on the stud contacts the head. might want to have a head in place to be sure they are aligned with the head as you install them.

I prefer #2 or Aviation Permeated. Some folks like to use Teflon tape. I also like the idea of using Anti-seize on the sides of studs. I like to use a thread cleaning tool to clean the internal threads in the deck prior to installing studs. NEVER USE A THREAD CUTTING TAP or DIE on these threads! Then I install studs hand tight, without torquing them.
