Rubber plugs in bottom of cylinders

[hotrodbanshee]

When installing new rubber plugs on the bottom of the stock cylinders in the water jackets should I use any type of sealent on them or put them in dry? Thought bout using the same sealent on them as I use to seal the cases together. Also do any of u guys use the high heat copper gasket spray on the base gaskets between the cases and cylinders?

Ok I just read in my clymer manual and they say to use Gasgacinch on the plugs before installing.
