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.
