I have a tube of Permatex Form-a-gasket #2 and a tube of Permatex Ultra black. Are either of these ok to use on the gaskets? It's been so long since I installed a water pump that I don't remember what I used the last time.

If using a motorplate, I don't use gaskets at all. Just a light coat of ultra grey silicone.

Their part # is 22071, works good , last a long time I use it on the gasket (both sides) on the thermostat housing only, not on the water pump to block gaskets Mr.Cab Racing and winning with Mopars since 1964.

Then screw these into the block when installing the water pump housing and seal they act as guides.. Makes the job much easier without having the gasket slip down. Then 1 by 1 unscrew the studs and install the proper bolts and torque things down.. Just my $0.02...

I totally agree, I do this on other areas including the heads live every 24 hour block of time like it's your last day on earth

I use ARP 12 point stainless for all builds and put a thin coat of ARP bolt lube on the threads. ARP stainless are the only bolts I use unless the application requires something specific such as rod bolts.
