I use the RVT on the housing side. You may want to put a straight edge across the housing to check for flatness.

Is it ok to double up a gasket on the thermostat housing? I have a small drip that can't be stopped and I noticed that the thermostat housing rocks back and forth on the intake and I tried to balance it out some but still not great. If it is ok to double up do I need to use RTV or ultra copper also? Thx
if it rocks that should tell you something.is it the chrome one by chance? i had to work mine over to get it true. then used the red gasket sealer

it's severely warped. Drawfile it (& the flange it sits on) & see if you can get it flat

Contact Moparts member here Gregg Travis AKA Roadhazard for the gasket you need.He makes a few different types for whatever housing you are using. Got his gaskets on my w.pump housing with a motor plate with zero sealer and ZERO leaks.I also am using a chrome water neck and one of his gaskets dry with zero leaks there as well Best darn gaskets money can buy Gus

If it is 1 of those chrome Mopar Performance Chinese specials... Toss it in the dumpster, you can sand it, grind it, put multiple gaskets and layers of RTV it will still leak.. The problems is the low quality recycled material used....
Get yourself an OE cast iron clone from Napa or the nice billet one from Mancini..
Just my $0.02...

Had on of those same things replaced the neck and gasket with a thin layer of mopar gray sealant and problem solved.

I use the brown permatex to seal it....Used to apply the Blue RTV ..
As for the rocking...take it off and file it down. It can't be that hard. Go in single motion in one direction. I had to file my one cast iron HP manifold and it took me 10 hours over 2 days to do so. Don't double up the gaskets because the gaskets will probably end up blowing out while you are on the road and then you will wish you had done it the right way. If you gotta get the car somewhere fast, then yeah...double up...but don't leave it accident prone.
