Keep sucking oil into engine via intake gaskets.

This causes an internal oil leak and vacuum leak making engine untunable.

I've been using Felpro 1284s. I've the retorque after the first heat cycle and it looks like they never really seal.. Is there a thicker/better LT1 gasket?

Check out the oil covered gaskets..

theres an excellent chance, if your not the cars engines original owner , that if your using used parts that either the intake or the heads were at some time in the past ANGLE MILLED, and since your leaks on the lifter gallery side chances are much better that its the intake that was milled
