Getting ready for final yblock assembly and curious about best sealers for the different gasket applications throughout the motor? Also is coppercoat spray a wise choice for the Felpro non-steel head gaskets?

If you have the blue FelPro composition head gaskets, they are the ‘Permatorque’ series and work best with no sealer.  They have a proprietary coating on them that eliminates the need for additional sealer.  Been awhile since I used any FelPro gaskets in a Y build but CopperCoat should work on all the gaskets other than the head gaskets.
 
For the Best Gasket brand of gaskets for the Y engines, I use white grease for the oil pan and intake manifold gaskets and CopperCoat for the timing cover gasket.  WD40 works well for the Best Gasket head gaskets.

Thats interesting, I have never heard of using WD40 on the head gaskets. I used the Best gaskets and if I remember correctly they said to use the CopperCoat so I did.

Copper coat on the head gasket makes it very difficult to remove the heads in the future.  I'd avoid it unless absolutely necessary.

This is the first time I have used Best gaskets and did what they recommended. Hopefully I won't have to remove the heads in my life time. The engine only has 8,000 miles on it now and I don't put a lot of miles each year.

Everyone seems to do what works for them. I still like Permatex #2 on one side of many gaskets especially where there is water or oil. I grease the opposite side for easier removal if necessary. When I replaced the intake on mine I didn't use anything around the ports but did on the water holes. The valley pan got Permatex and grease. No leaks in 3 years. Good luck.
