Dont use copper exhaust manifold gaskets either. Never could get those things to seal right.

They don't make ARP exhaust studs for the 420a. I would have got those if they did. I use the MLS gasket that comes with the kits. Have always used those on the exhaust manifold and have always worked fine. But when you're missing a bolt, it doesn't form the best seal. Wanted to try to spray that copper gasket sealer on the gasket but was pouring when I did it yesterday so would have been ineffective and wash right off.
