Gasket sealer recommendations for Intake, pan, and timing chain cover (360)

I have never heard of a one piece oil pan gasket for the LA engines. But as to the intake gaskets, I have built engines for 43 years, I do not like RTV for the end pieces. I have always used and prefer the actual cork gaskets for this location, the gaskets should be placed dry, use a little sealer in the corners only, torque to specs. I have done this for years and never had a leak of any kind. Same applies to the oil pan. For your water surfaces (water pump, timing cover ) I use Permatex Form a gasket stage 2 non-Harding, it expands and contracts with temperature to maintain seal. Have fun!
