Hello, In preparing for my 3800sc swap, I'm going to be replacing some gaskets on the 3800sc motor before installing. I will be replacing the following gaskets:
Lower intake manifold
Supercharger
Oil filter adapter
Oil pan
Front and rear main seal
And I'm there are some others that I'm forgetting right this minute.

I have never redone gaskets before so I was wondering if I need to use RTV on everything, some of those, or if its not needed at all.
Thanks
I'm sure there will be more questions as I tear the motor down a bit.

Most gaskets do not use RTV Silicon. Some go dry or w/ High Tack sealer.
Examples:
L4 w/ best valve cover gasket go dry. Rubber or Cork use High Tack only.
Some oil pans use it but in small amounts and only in a few places, not whole gasket.

You need Torque values on bolts etc. Aluminum parts and others are easy to wreck.
Most torque specs are on clean and dry parts and bolts/nuts. Any lube, including anti seize, then torque to specs can break things.

A few other notes...
Front Main often need sleeve on old balancer or replace the balancer. If balancer have issues then new seal will leak.
Drive-in seals need a coat of High Tack or Super “300” (both are paint type) in hole you drive the seal. Like axle and Front Main seals.
