Header Bolt Sealant - What's Everyone Using?

[Mtrhed]

Hi everyone,
I'm new to mopars and while removing the TTI headers from my 440 powered '68 Dart I noticed that the header bolts go thru the water jacket on the heads. What type of sealant does everyone use on header bolts to prevent water leaks? I didn't see any residue from any sealant when I took to bolts out. I'm planning on using Mr. G's copper header gaskets and ARP stainless bolts to complete the installation. Thanks for any advise you may have.

I used Permatex high temp thread sealant.

Makes sense, thanks for the reply.

I would add to use studs on the 4 corners instead of bolts....
Make installing easier and you don't have to break the seal when removing the headers.
