well some times people put a lot of rtv on the valve cover gaskets and it oozes down onto the intake. But if there is rtv coming from underneath the intake manifold then that would be an issue that needs to be remedied by installing new gaskets.
use Edelbrock 7201 or felpro 1256 gaskets. The blue steel core ones are for stock cast iron intakes and will never seal properly on the aluminum intakes.
When applying rtv to intake gaskets. Think all that stuff oozing out is also oozing into your ports as well. it goes every where. Use a gasket adhesive like gasacinch or permatex's high tack spray a gasket sealer, to hold the gaskets in place. you can use a couple bolts to hold the gaskets where you want until the spray sealer sets up.
Use the rtv to seal up the end seal areas by applying a good 1/4 inch bead along the block end walls overlapping a little bit onto the intake gaskets where they meet. let that set up for a cood 1/2 hour. Then very carefully lower your intake with out disturbing the silicone or gaskets looking at the bolt holes to line it up. once it is set in place install your bolts and snug them up. wait 1 hour and tourqe to specs 25 ft lbs.
