Exhaust bolt/stud sealer

What do you use to seal the exhaust bolts/studs in the heads on your big block? I am using ARP bolts, and I've never really used sealer before, and I've also never had them leak. So I guess I'll try it this time.
Thanks!

Some use gold Permatex.I use silver anti sieze and never had a leak with bolts.Now I run studs in my headers with just a bolt where a stud wont go.Rocky

I used ARP bolts for the first time. Never had a problem before now. I'm guessing the oxide finish is too smooth?

I'd highly suggest using OE shouldered studs & trim the outer fine threaded portion till just enough threads remain so the nut fits flush. Any more length is a waste & hampers header fitment. You can also source a higher grade nut that is thinner so you can trim em even more. To ans your Q I would suggest Permatex #1 gasket cement in the toothpaste like tube. It is thick/viscous & dries rock hard. "the right stuff" gasket cement tho pricey is even better. Clean the holes with a small bottle brush/brake kleen first till the holes are clean & dry so the cement will get a better grip

Can anyone give me a part # for an ARP stud kit that will fit our 906 heads? (Header application)
Looked at various sites, but came up empty on a kit that referenced BB MOPAR??

Thanks, Joe

I didn't use studs, they are 3/8 headed shoulder bolts. Thank you.

Dorman makes the studs.I bought new ones at a local auto parts store.I even got thick washers there.Total was about 12 bucks.I even run studs in my aluminum heads with no water at the holes.Rocky
